The Irresistible Allure of Ninja Foodi & Instant Pot Chili Mac
If you’re already familiar with our extensive collection of Instant Pot recipes, you’ve likely encountered our classic Instant Pot chili mac recipe, which has long been a cherished favorite. However, this updated version takes that beloved dish to an entirely new level of deliciousness! We’ve amplified the flavors with the addition of zesty diced chiles, fresh green onions, and an abundance of rich, melted cheese. You’ll truly taste the difference, making it a delightful dilemma to decide which version your family loves best. Why not rotate them throughout the week for variety? Let’s dive into the essential ingredients that make this chili mac so spectacular.

Essential Ingredients for Your Pressure Cooker Cheesy Chili Mac
One of the many beauties of this recipe is its reliance on readily available ingredients, many of which are likely already in your pantry. With just a few canned goods, some ground meat, and a handful of other staples, you’re well on your way to a comforting meal.
- Your Preferred Pressure Cooker:
- Whether you’re using a Ninja Foodi pressure cooker and air fryer, a classic Instant Pot, or a Crock Pot Express, this recipe adapts beautifully.
- For Instant Pot users, we highly recommend investing in a non-stick inner pot for easier cooking and cleanup, especially when dealing with pasta.
- Protein Powerhouse: Opt for spicy ground sausage for an extra kick and depth of flavor – it’s our personal favorite! However, lean ground beef works wonderfully too if you prefer a milder taste or are catering to different dietary preferences.
- Aromatic Base: Onion, finely diced, adds a foundational layer of flavor. While optional, it significantly enhances the overall profile of the chili mac.
- Canned Diced Chiles: These add a subtle heat and a touch of authentic chili flavor without being overwhelmingly spicy.
- Chili Seasoning Packet: A convenient way to infuse your chili mac with a balanced blend of traditional chili spices.
- Tomato Sauce: Contributes to the rich, saucy texture and classic tomato base of the dish.
- Diced Tomatoes: We prefer petite diced tomatoes for their finer texture, ensuring they blend seamlessly into the sauce. They add a vibrant freshness and acidity.
- Kidney Beans: A staple in any good chili, providing texture, protein, and a hearty element. No need to drain them!
- Elbow Macaroni Noodles: The “mac” in chili mac! These small, curved noodles absorb the delicious chili sauce perfectly.
- Beef Broth: Provides the necessary liquid for cooking the macaroni and helps create a rich, savory sauce.
- Salt and Pepper: To taste, essential for seasoning and bringing out all the flavors.
- Plenty of Cheese: The star of the show! We recommend sharp cheddar or a cheddar and Monterey Jack blend for maximum meltiness and flavor.
- Chili Powder (Optional): If you crave extra heat, a little chili powder can be added. If you’re using spicy sausage, you might find it unnecessary.

The cooking process begins with a simple sauté function to brown your chosen ground meat. You only need to cook it until the exterior is no longer pink, as it will continue to cook through during the pressure cooking phase. After this initial step, it transforms into a convenient “dump and go” meal, making it incredibly easy for even novice cooks to master.
- The foundation of this amazing chili mac is our time-tested 5-ingredient Crockpot chili recipe, a beloved classic that has graced our tables for years and remains a widely popular post on our blog.
If you’re in the mood for a hearty chili dinner without the pasta, simply omit the noodles. This recipe offers a quick and easy way to enjoy a rich, cheesy chili with minimal cooking time, making it perfect for those busy weeknights.
Elevate Your Chili: Unveiling Secret Ingredients
Every great cook knows that a little secret ingredient can transform a good dish into an extraordinary one. When it comes to chili, the possibilities for enhancing flavor, adding a unique twist, or simply spicing things up are endless. Here are a few fantastic ideas to make your chili mac stand out:
- Sweetness and Depth: A tablespoon of honey or a splash of dry sherry (substituted for some of the broth) can add a subtle sweetness and complex depth that beautifully balances the savory notes of the chili.
- Thickening and Texture: For a thicker consistency and a delightful, subtle polenta-like touch, stir in a few tablespoons of cornmeal. It’s a fantastic way to add body to your chili.
- Unexpected Richness: Don’t knock it ’til you try it! Replacing a portion of the liquid with carbonated dark soda (like cola or root beer) can introduce a unique sweetness and richness, adding a surprising complexity to your bowl.
- Bright Citrus Kick: A squeeze of fresh lime juice over your finished chili mac, along with extra shredded cheese, provides a bright, zesty counterpoint that truly awakens the palate.
- Hidden Veggies: Finely shredded zucchini is virtually undetectable in the dish but adds a healthy boost of nutrients and moisture, making it an excellent way to sneak in extra vegetables, especially for picky eaters.
- Fiber Boost: For an easy way to increase your dietary fiber intake without altering the taste, stir in a tablespoon of flax seeds. You won’t even know they’re there, but your body will thank you!

Mastering Chili Mac in Your Pressure Cooker: Tips for Success
Making this easy chili mac recipe in a pressure cooker is straightforward, but a few key tips will ensure perfect results every time:
- Start with Sauté: Begin by turning your pressure cooker to the sauté function and adding a small amount of olive oil. Brown your ground meat (sausage or beef) until it’s mostly cooked through, with just a hint of pink remaining.
- Soften the Aromatics: Shortly after adding the meat, stir in your diced onions. This allows them time to soften and release their sweet flavors. Feel free to add about 1/2 cup of diced bell peppers here for extra color and nutrition.
- Infuse with Flavor: Once the meat is nearly browned, sprinkle in your chili seasoning packet. Stir it well to ensure the spices evenly coat the meat, enhancing the overall chili flavor.
- Layer and Stir Liquids: After turning off the sauté function, add all your canned ingredients (tomato sauce, diced tomatoes, kidney beans, diced chiles) and beef broth to the pot. Stir these ingredients thoroughly to combine them into the flavorful chili base.
- The Macaroni Magic – NO STIRRING: This step is crucial for preventing a “burn notice.” Carefully pour your uncooked elbow macaroni noodles on top of the liquid. Gently submerge them into the liquid with a spoon, ensuring they are mostly covered, but **do not stir them into the chili base.** Stirring can cause the noodles to clump at the bottom and potentially trigger a burn error.
- Pressure Cook to Perfection: Secure the pressure cooker lid and close the steam valve. Set your appliance to pressure cook on high for 5 minutes.
- Cheesy Finish: Once the cooking cycle is complete, perform a quick release of pressure. Carefully open the lid. Stir in 1 cup of cheese until it’s beautifully melted and integrated into the chili mac.
- Optional Golden Topping:
- If you own a Ninja Foodi, you have the advantage of an air fryer function! Sprinkle the remaining cup of cheese evenly over the top of the chili mac, close the air fryer lid, and set it to “Air Crisp” at 390 degrees F for about 4-5 minutes, or until the cheese is melted and golden brown. Watch it closely to prevent burning.
- For Instant Pot or Crock Pot Express users without an air fryer function, simply stir in the second cup of cheese. Alternatively, you can transfer the chili mac to an oven-safe baking dish, sprinkle the cheese on top, and broil it in a preheated oven for 4-5 minutes until the cheese is bubbly and lightly browned.

To Drain or Not to Drain? The Ground Meat Debate
When cooking ground meat for chili, a common question arises: should you drain the fat? My personal preference is to **not drain the meat**, and here’s why. We often source lean, organic ground beef, which naturally produces very little excess fat once browned. The small amount of fat that does render out contributes significantly to the overall flavor and richness of the dish. Even when I’ve used 80/20 ground beef in the past, I typically skipped draining it.
- Draining the fat can sometimes lead to a blander chili. That small amount of rendered fat carries a lot of flavor, and when distributed throughout the dish, it enhances the savory notes of the chili. Of course, moderation is key, and if you prefer a leaner dish, feel free to drain some of the fat. But for maximum flavor, I highly recommend keeping it in!
This ultimate comfort food truly shines in a Ninja Foodi. After stirring in a generous amount of cheese, I added another layer on top and closed the air fryer lid. A quick check at 390 degrees F for about 5 minutes resulted in a perfectly melted, golden-brown cheese crust. Oh, it was utterly fantastic!
- Remember, this recipe is adaptable to any pressure cooker you have. It works beautifully for a Crock Pot Express chili mac as well. I simply love sharing the results from my Ninja Foodi because the ability to quickly pressure cook AND achieve a crispy, browned top is an incredible feature that truly elevates dishes like this.

Reheating and Storing Your Cheesy Chili Mac
Chili mac makes excellent leftovers, often tasting even better the next day as the flavors meld and deepen. Proper storage is key to enjoying it later:
- Refrigeration: Store any cooled leftovers in airtight containers in the refrigerator for up to four days.
- Freezing: For longer storage, chili mac freezes beautifully for up to four months. Portion it into freezer-safe containers or bags. Thaw overnight in the refrigerator before reheating.
- Microwave Reheating: For a quick reheat, transfer a portion to a microwave-safe dish and heat on high, stirring occasionally, until steaming hot throughout.
- Oven Reheating: To reheat a larger batch or achieve a fresher texture, transfer thawed chili mac to an oven-safe dish, cover loosely with foil, and bake at 375 degrees F (190 degrees C) for 20-30 minutes, or until bubbling and hot. If desired, remove foil for the last few minutes to lightly brown the top. You can even reheat it straight from the freezer in the oven, though it will take longer.
Customizing Your Instant Pot Cheesy Chili Mac: Endless Variations
While the base recipe for this Instant Pot cheesy chili mac is fantastic on its own, it’s also incredibly versatile, lending itself well to various additions and customizations. Feel free to get creative and tailor it to your family’s preferences. Here are a few favorite add-ins you could consider, typically around 1 cup in total, depending on your desired outcome:
- More Vegetables: Add diced bell peppers (red, green, or yellow) along with the onions during the sauté step for extra color, sweetness, and nutrients.
- Kick Up the Heat: For those who love a serious spicy kick, finely chopped jalapeño peppers can be added with the onions. Or, stir in a dash of sriracha seasoning or hot sauce at the end for immediate heat and flavor.
- Bean Bonanza: If you’re a big fan of beans, consider adding a can of black beans (drained and rinsed) along with the kidney beans. This adds another layer of texture and protein.
- Zesty Tomato Boost: For an extra layer of zesty tomato flavor and a bit more liquid, a can of Rotel (diced tomatoes with green chiles) can be added in addition to or in place of the plain diced tomatoes. Ensure there’s still enough liquid for the macaroni to cook properly.
- Smoky Flavor: A pinch of smoked paprika or a dash of liquid smoke can impart a wonderful smoky depth to your chili mac.
- Sweet Corn: Stir in a can of drained corn or a cup of frozen corn kernels at the end for a touch of sweetness and vibrant color.

- 1 pressure cooker
Ingredients
- 1 lb ground sausage (spicy is best, or ground beef)

- 1 packet chili seasoning, 1 oz
- 1 can diced tomatoes, 14.5 oz (we prefer petite size)
- 1 can kidney beans, 14.5 oz (not drained)
- 1 can chiles, diced, 4 oz
- 1 can tomato sauce, 8 oz
- 1 c beef broth
- 1 c elbow macaroni, uncooked
- 2 c cheese, shredded (sharp cheddar is best, or a cheddar/jack mix)
- 1/4-1/2 tsp chili powder, optional for extra heat
- 1.5 tbsp olive oil
- Salt and pepper to taste
Instructions
- Turn your pressure cooker to the sauté function (or sear/brown on Crock Pot Express). Add olive oil, then your ground sausage or beef, and diced onions.
- Cook until the meat is no longer pink, stirring occasionally. Halfway through the cooking process, add the packet of chili seasoning and stir to combine. Once meat is browned, turn the pot off.
- Add the tomato sauce, diced tomatoes, kidney beans (undrained), diced chiles, and beef broth to the pot. Stir all these ingredients well to create the chili base. Add chili powder now if desired for extra heat, and season with salt and pepper to taste.
- Pour the 1 cup of uncooked macaroni noodles on top of the liquid mixture. Gently push them down with a spoon so they are just submerged in the liquid. **DO NOT stir the macaroni into the chili base.** This is crucial to prevent a “burn” notice.
- Close the pressure cooker lid and ensure the steam release valve is sealed. Set the cooker to pressure high for 5 minutes.
- Once the cooking cycle is complete, perform a quick release of pressure. Carefully open the lid. Stir in 1 cup of the shredded cheese until it has melted and is fully incorporated.
- For a golden, bubbly top (Optional):
- If you have a Ninja Foodi: Sprinkle the remaining 1 cup of cheese on top of the chili mac. Close your air fryer lid and set the appliance to “Air Crisp” at 390 degrees F (200 degrees C) for 4-5 minutes, or until the cheese is melted and lightly golden. Watch it closely to prevent burning.
- If you have an Instant Pot or Crock Pot Express: You can simply stir in the second cup of cheese. Alternatively, transfer the chili mac to an oven-safe baking dish, sprinkle the cheese on top, and place it under your oven’s broiler for 4-5 minutes until the cheese is melted and golden brown.
- Serve immediately! For an extra indulgent touch, add a small dollop of sour cream or a sprinkle of fresh green onions on top of each serving. Enjoy!
