Instant Pot Million Dollar Casserole
Mmmm-mmm! When I think about Instant Pot million dollar casserole I want to dive into the pot and eat it all up! It was such a winner at my house. Layers of spaghetti, meat, sauce, cheese and sour cream were enjoyed thoroughly!
I used my cool new Instant Pot Duo Crisp 11-in-1 Multi-Use Pressure Cooker and Air Fryer* to make this recipe all in one pot. First you brown the meat using the sauté setting. Then you pressure cook the spaghetti (no draining!). Finally you use the air fryer lid to bake the casserole. One pot to do 3 different things! It was so convenient. The traditional way of making this recipe requires browning the meat in a frying pan, boiling the noodles in a pot and then baking in the oven in a 8×8 inch dish. Too many dishes for me! I’ll be making this in the Instant Pot from now on!

- You can use ground beef or ground turkey for this recipe
- I used the last of a box of white, thin spaghetti and some whole wheat spaghetti. You can use whatever you have on hand! I know you can buy spaghetti at the store that has already been broken up too (vermicelli or fideo).
- You can also make this recipe with egg noodles. I would only pressure cook the egg noodles for 1-2 minutes though.
- Use your favorite spaghetti sauce. I used a can of Hunts. I also like Classico sauces.
- If you don’t like cottage cheese try using ricotta cheese or cream cheese.
- I used cheddar to top the casserole but you can also use other types of cheeses like mozzarella, parmesan, monterey jack etc.

Notes
I used my 6 Quart Instant Pot Duo Crisp 11-in-1 Multi-Use Pressure Cooker and Air Fryer* If you don’t have an air fryer lid you can make bake this in the oven. Spread the pressure cooked spaghetti into a baking dish, top with sour cream mixture and spaghetti sauce and then bake in the oven for 25 minutes at 350° F. Add the cheese on top and bake for 5 more minutes.

Hi Karen,
Can I freeze the leftovers or cut the recipe in half? Thanks in advance.
I would cut the recipe in half. I’m not sure how this one would freeze!
It freezes just fine.
isn’t this pretty much the same as your https://www.365daysofcrockpot.com/instant-pot-sour-cream-noodle-bake/ recipe? few very minor tweaks..
Similar. But this one is made with spaghetti sauce and spaghetti noodles. The other is made with egg noodles, seasonings and tomato sauce. Both are great!
I would like to cook this. Would it be possible to cook in the pot n pot. Then put inner pot in Air Fryer or oven?
Hmmm, I’m sure it would be possible. As far as timing goes though I’m not 100% sure. pot in pot seems so take at least double the amount of pressure cook time. You may have to experiment with it to get it exactly right.
Thank you so much. I will cook it as the recipe states.

How can you rate 5 stars when you haven’t even made it? I’d like to try this but looking to see who’s already made it & rated it
I’m always trying to stay low carb…so we have some cooked spaghetti squash in the freezer. Could I sub this for the spaghetti? How would this change the PC time? Maybe just a minute a 2? Do you plan to do some low carb recipes?🤞🏻😄
Here are my low carb recipes: https://www.365daysofcrockpot.com/recipes/?fwp_method=instant-pot&fwp_dietary_restrictions=low-carb
I’d do 2 minutes for the squash (if it’s not in it’s shell)
