I remember my mom’s baked mac and cheese: boiled pasta, a rich cheese sauce, buttery breadcrumbs, and the oven finish. It was a bit of work, but always comforting and totally irresistible. This Instant Pot version captures that creamy, nostalgic comfort with far less effort and fewer steps.
The key to a smooth, lump-free sauce is pressure-cooking the pasta first and adding the dairy afterward. The cream cheese in this recipe creates an ultra-silky texture that blends beautifully with sharp cheddar and Gruyere for depth. That said, you can customize with your favorite cheeses or whatever you have on hand.

- Water or low-sodium chicken broth
- Kosher salt

- Cream cheese, at room temperature
- Garlic powder
- Dry mustard
- All-purpose flour (or a thickener of choice)
How to make macaroni and cheese in the Instant Pot
- Pressure-cook the pasta first, then add dairy. Milk and cheese proteins can separate under high pressure. Cook the pasta under pressure and add milk, cream cheese, and shredded cheese afterward to keep the sauce smooth.
- Use room-temperature cream cheese. Soft cream cheese melts and blends more evenly. If cold, cut into small cubes and briefly warm to avoid separation.
- Mix cheeses for better flavor. Combining a sharp cheddar with a nutty cheese like Gruyere gives complexity and a balanced, rich flavor.
What to serve with Instant Pot macaroni and cheese

How to store leftover mac and cheese
Allow leftovers to cool to room temperature, then transfer to an airtight container and refrigerate for 3–5 days. Reheat gently on the stovetop over low to medium-low heat with a splash of milk, stirring to restore creaminess. The microwave also works—heat in short intervals, stirring between sessions.
Frequently asked questions
You can freeze it, but texture can change. For best results, portion leftovers into smaller containers, remove excess air, and freeze. Thaw overnight in the refrigerator and reheat gently on the stove with a splash of milk.
Yes. One batch yields roughly 6 cups; doubling will yield about 12 cups. If your Instant Pot is large enough, you can cook a double batch, otherwise cook in two batches.
Cut it into small cubes and let it warm slightly at room temperature or brief intervals in the microwave to prevent lumps when stirring into the hot pasta.
Substitutions
Make it gluten-free: Use a gluten-free pasta and replace flour with 3/4 teaspoon cornstarch or arrowroot mixed with a little water to thicken the sauce. For dairy-free options, use plant-based milk and dairy-free cheeses, though texture and flavor will differ.
