🥘 Instant Pot vs. Stovetop Mac & Cheese

Why choose the Instant Pot over the stovetop method? The Instant Pot simplifies the process by combining cooking steps into one vessel and often cuts overall time.

Less mess, less fuss. You can pressure cook the pasta and finish the sauce in the same pot, which reduces cleanup and speeds things up.

The Instant Pot is versatile: sauté, pressure cook, slow cook, and keep warm. It’s ideal for one-pot comfort recipes like mac and cheese, chicken and rice, salsa chicken, or cheesy dips.

👨‍🍳 How to Make Instant Pot Macaroni and Cheese

1. Cook the pasta. In the Instant Pot combine 24 oz macaroni, 2 tsp salt, 2 tsp black pepper, 2 tbsp yellow mustard, 1 tbsp hot sauce, and 4 cups water (or chicken broth). Seal the lid and cook on manual, high pressure, 4 minutes. Quick release when the time is up.
2. Finish the sauce. After releasing pressure and opening the lid, add 12 oz evaporated milk, 10.5 oz condensed cheddar cheese soup, 8 oz cream cheese, 2 cups shredded cheddar, and 2 cups shredded Colby Jack. Stir thoroughly until the cream cheese and shredded cheeses melt and the sauce comes together. It may look thin at first but will thicken as you stir and as the pasta releases starch.

That’s all there is to it. This method is forgiving and perfect for beginner Instant Pot users while delivering a creamy, homemade result.

Alternate Method: Slow Cooker

To make this in a slow cooker, omit the water. Add all ingredients except the dry pasta to the slow cooker and cook on low for 3–4 hours. Cook the pasta separately to al dente about 30 minutes before serving and stir into the sauce.

Alternate Method: Stovetop

For stovetop preparation, bring the water, mustard, hot sauce, salt, and pepper to a boil in a large pot, add the pasta and cook to al dente. Drain the pasta, return it to the pot, and stir in the evaporated milk, cheese soup, cream cheese, and shredded cheeses over low heat until smooth and combined.

🍽️ Great Dinner Pairings

• Pulled BBQ chicken sandwiches

• Roasted or baked chicken dishes

🥡 Leftovers & Storage Tips

Store leftovers in an airtight container in the refrigerator for 3–4 days. Pasta dishes can absorb other odors, so a tight seal is important.

Reheating: Microwave single servings for about 45 seconds, stir, and add 20–30 seconds if needed. Add a splash of milk while reheating if the sauce has thickened or dried out.

Freezing: This mac and cheese freezes well. Portion into quart-sized freezer bags (3–4 portions per bag), freeze flat, thaw overnight in the fridge, and warm gently before serving.
