It’s quick, easy, and results in perfectly tender pasta coated in rich, cheesy sauce every time.

Ingredients
- 2 cups (200g) elbow macaroni or any pasta shape of your choice
- 2 cups (480ml) whole milk or half-and-half for extra creaminess
- 1 cup (120g) shredded sharp cheddar cheese
- 1/2 cup (60g) grated Parmesan cheese
- 2 tablespoons unsalted butter
- 1 teaspoon Dijon mustard (optional, adds depth)
- 1/2 teaspoon salt (adjust to taste)
- 1/4 teaspoon black pepper
- 1 teaspoon garlic powder (optional)
- 1 teaspoon smoked paprika or regular paprika (optional for flavor)
- 1 tablespoon cornstarch (optional, for thickening)
- 1 tablespoon water (to mix with cornstarch)
Instructions
- Prepare the Instant Pot: Add the pasta, milk, butter, salt, pepper, garlic powder, and Dijon mustard (if using) into the Instant Pot. Stir to combine and ensure the pasta is submerged in the liquid.
- Cook the pasta: Close the lid and set the valve to sealing. Cook on high pressure for 4 minutes. It will take about 10 minutes for the pot to come to pressure.
- Quick release: Once the cooking time is up, carefully perform a quick release by turning the valve to vent to release the steam. Open the lid once the pressure subsides.
- Stir and melt cheese: Stir the pasta gently to distribute the heat. Add the shredded cheddar and Parmesan cheese, along with the butter. Stir until the cheese melts and the sauce becomes creamy. If the sauce is too thin, you can thicken it with cornstarch.
- Thicken the sauce: In a small bowl, mix the cornstarch with water to create a slurry. Pour this into the pasta mixture and stir well. Turn on the ‘Sauté’ mode for 1-2 minutes until the sauce thickens to your desired consistency.
- Adjust seasoning and serve: Taste and adjust salt and pepper if needed. Serve hot, garnished with extra cheese or herbs if desired.
Tips
- Cheese options: Feel free to experiment with different cheeses like Monterey Jack, Gruyère, or even a touch of blue cheese for a flavor boost.
- Milk substitutions: For a richer sauce, use heavy cream or half-and-half. For a lighter version, skim milk works but may result in a less creamy texture.
- Avoid overcooking: Do not cook the pasta longer than 4 minutes under pressure, as it can become mushy. Quick release helps prevent overcooking.
- Storage tips: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of milk to loosen the sauce.
Serving Suggestions
Serve your Instant Pot mac and cheese as a main dish with a side of steamed vegetables, a crisp green salad, or some garlic bread for a complete meal. It also pairs well with grilled chicken or sausage for added protein. For a fun twist, top with crispy bacon bits, chopped scallions, or a sprinkle of hot sauce.
Variations
Customize your mac and cheese by adding cooked vegetables like peas, spinach, or roasted tomatoes. Stir in cooked bacon, shredded chicken, or lobster for a decadent seafood version. You can also spice it up with jalapeños or hot sauce for a spicy kick. For a vegan version, substitute dairy cheeses with plant-based cheeses and use plant-based milk, ensuring the dish remains creamy and flavorful.
Storage and Reheating
Leftover mac and cheese can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, transfer to a microwave-safe dish or a saucepan, adding a splash of milk or water to loosen the sauce. Reheat on medium power in the microwave in 30-second bursts, stirring in between, or on the stove over low heat until warmed through. Avoid overheating to prevent the cheese from becoming stringy or the pasta from drying out.
Frequently Asked Questions
Can I use other pasta shapes for this recipe?
Absolutely! While elbow macaroni is traditional, you can use penne, fusilli, shells, or even gluten-free pasta. Keep in mind that cooking times may vary slightly depending on the shape and size.
How do I prevent the cheese from becoming grainy?
To avoid graininess, add the cheese gradually and stir well after each addition. Use freshly grated cheese rather than pre-shredded varieties, as they often contain anti-caking agents that can affect melting. Also, make sure the heat is gentle when melting cheese.
Can I make this recipe ahead of time?
Yes, you can prepare the mac and cheese in advance. Store it in the refrigerator for up to 3 days. Reheat gently on the stove or microwave, adding a splash of milk to restore creaminess. However, note that the texture may slightly change upon reheating.
Is it possible to make this vegan?
Yes! Use plant-based cheeses and non-dairy milk like almond, soy, or oat milk. Choose vegan butter or olive oil instead of butter. The flavor and creaminess can be maintained with the right cheese substitutes and seasonings.
What if my pasta is undercooked after pressure cooking?
Ensure you’re using the correct cooking time—about 4 minutes at high pressure. If undercooked, you can close the lid again and cook for an additional minute or two, but be careful not to overdo it to prevent mushiness. Quick releasing pressure helps stop the cooking process immediately.
Can I double the recipe?
Yes, you can double the ingredients, but be mindful not to exceed the maximum fill line of your Instant Pot. Adjust cooking time if necessary and ensure there’s enough liquid to prevent burning. It’s best to cook in batches if your pot isn’t large enough.
