Substitutions
- Pasta: Elbow macaroni can be swapped with shells, cavatappi, penne, or any small pasta that holds sauce well.
- Cheese: Cheddar and mozzarella can be replaced with Monterey Jack, Colby, Gouda, or a sharp white cheddar for extra flavor.
- Harissa paste: If you don’t have harissa, use sriracha, chili garlic sauce, or a mix of tomato paste + cayenne pepper for a similar spicy kick.
- Milk: Whole milk gives the creamiest texture, but you can also use 2% milk, evaporated milk, or unsweetened oat milk.
- Butter: Can be substituted with olive oil or ghee for a slightly different flavor profile.
- Smoked paprika: Regular paprika or a pinch of cayenne pepper can be used instead, depending on your spice preference.
Equipment
- Instant Pot or Electric Pressure Cooker
- Measuring Cups and Measuring Spoons

Storage
Store any leftover Instant Pot harissa mac and cheese in an airtight container in the refrigerator for up to 3–4 days. The sauce will thicken as it chills, so add a splash of milk when reheating to bring back its creamy texture.
Reheat gently in the microwave or on the stovetop over low heat, stirring occasionally until warmed through. Freezing is not recommended, as the cheese sauce may separate and become grainy once thawed.
Recipe Tips
FAQ
Can I make this Instant Pot harissa mac and cheese less spicy?
Yes, simply reduce the harissa paste to 1/2 tablespoon or omit it entirely for a mild, classic creamy mac and cheese.
What is harissa paste?
Harissa is a North African chili paste made with roasted red peppers, chili peppers, garlic, and spices. It adds a smoky, slightly spicy depth of flavor.
Can I use a different pasta shape?
Yes, small pasta shapes like shells, cavatappi, or penne work well as long as they hold the cheese sauce.
Why is my mac and cheese grainy?
This usually happens if the cheese is added too quickly or if pre-shredded cheese is used. Always add freshly grated cheese slowly over low heat.
