How to Make Instant Pot Chili Mac and Cheese Recipe

Step 1: Brown the Beef and Onion

Start by setting your Instant Pot to sauté mode. Add the ground beef and diced onion, cooking until the beef is browned and the onion has softened to translucent perfection. This step builds a flavorful foundation by caramelizing the beef and unlocking the onion’s natural sweetness.

Step 2: Add Garlic

Stir in the minced garlic and let it cook for just about a minute until fragrant. Garlic is such a small ingredient but it packs a powerful punch, infusing the dish with that irresistible aroma that makes your kitchen smell like a cozy restaurant.

Step 3: Combine Pasta and Liquids

Next, add the elbow macaroni, beef broth, diced tomatoes, and drained kidney beans. This combination ensures tender, perfectly cooked pasta swimming in a deliciously soupy base that will soak up all those flavors in minutes.

Step 4: Season with Spices

Sprinkle the chili powder, cumin, salt, and black pepper over the mixture, stirring gently to incorporate. These spices are what give this Instant Pot Chili Mac and Cheese Recipe its signature warmth and zest, so don’t be shy here.

Step 5: Pressure Cook

Seal the Instant Pot lid and set the pressure cooker on high for 4 minutes. This short, high-pressure cooking time is the magic behind tender pasta and melded flavors without any mushiness or fuss.

Step 6: Quick Release and Add Cheese

Perform a quick release of the pressure to prevent overcooking. Then, stir in the shredded cheddar cheese. It should melt into the chili mac in a creamy, velvety swirl that transforms this dish into pure comfort food heaven.

Absolutely! Simply skip the ground beef and substitute with extra beans, lentils, or a plant-based meat alternative. The spices and cheese still deliver plenty of flavor and comfort.

Is this recipe gluten-free?
