Notes/Tips
- Serve with garlic bread and green beans.
- I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot.
- This recipe can easily be doubled or halved. Adjust ingredients, keep same cooking time.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
- If you use another type of pasta you may need to adjust the cooking time. Here is the formula: look at the back of the box of pasta and see how many minutes it says to boil the pasta. If it’s 10 minutes you divide that number by 2 (=5) and then subtract 2 minutes. So you would pressure cook for 3 minutes. I usually use a 5-10 minute natural pressure release for pasta.
- Other recipes you can make with macaroni are Instant Pot Chick-fil-A Mac and Cheese and Instant Pot Easy Breezy Casserole.
- The original casserole had diced green bell pepper and olives in it. Add if you’d like.
