Instant Pot Spasagna
Spasagna! It’s a fun word to try and say. I haven’t gotten it down quite yet. This recipe is a take on a restaurant named Cheddar’s spasagna dish (although it is no longer on the menu). Of course I changed a few things and used my Instant Pot to put it together.
I think you will love the outcome! It is really a delicious and fun meal. The creamy, cheesy spaghetti is good on its own but when you add a hearty meat sauce to the top it just brings it to a whole new level!
This recipe does make a large amount. We fed 11 of us with this dish. So if you’re not feeding a crowd you can easily halve the recipe. Just cut all the ingredients in half but keep the cooking time the same. If you’re baking in the oven use a square 9×9 inch dish instead of a 9×13 inch dish.
Ingredients/Substitution Ideas
- Spaghetti–or angel hair
- Chicken broth–or water and Better than Bouillon
- Sour cream–or plain yogurt
- Ricotta–or cottage cheese
- Half and half–or whole milk or evaporated milk
- Shredded parmesan cheese–or grated parmesan in the green can
- Shredded mozzarella cheese–or Italian blend
- Garlic powder
- Kosher salt
- Italian seasoning
- Black pepper
- Ground Italian sausage
- Spaghetti sauce–use your favorite marinara sauce
Steps
Break spaghetti in half and scatter it in Instant Pot in a criss cross pattern. Pour the broth into the pot. By spreading the spaghetti in a criss cross pattern you will prevent it from clumping together. The spaghetti won’t be completely covered by liquid and that is okay.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 4 minutes. When time is up let pot sit for 5 minutes and then move valve to venting. If foam starts escaping through the valve then move it back to sealing and wait 20 seconds before trying again. Remove the lid.

Do not drain any excess liquid in the pot. Stir in the sour cream, ricotta, half and half, parmesan, 2 cups of mozzarella, garlic powder, kosher salt, Italian seasoning and pepper.

Baking instructions with air fryer lid*: Once the mixture is well combined, pat it down in the pot in an even layer. Spread the sausage over the top of the pasta layer. Then pour the spaghetti sauce evenly over the top. Cover the Instant Pot with the air fryer lid. Use the bake button at 300° F for 20 minutes. After 20 minutes is up sprinkle the remaining ½ cup of cheese on top and bake for another 3 minutes. Serve and enjoy!
Baking instructions with oven: Once the mixture is well combined spread it in a 9×13 inch baking dish. Spread the sausage over the top of the pasta layer. Then pour the spaghetti sauce evenly over the top. Bake at 350° F for 30 minutes. Sprinkle the remaining ½ cup of cheese on top and bake for another 3 minutes. Serve and enjoy!



Notes/Tips
- Serve with a green salad and my favorite Olive Garden Italian Salad Dressing.
- I used my 6 quart duo crisp Instant Pot*. You can also make this in an 8 quart pot.
- Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
- To halve the recipe cut all the ingredients in half but keep the cooking time the same. If you’re baking in the oven use a square 9×9 inch dish instead of a 9×13 inch dish.
- The original recipe had 2 pounds of mozzarella cheese! I cut the cheese down to just 2 ½ cups. If you’re a cheese lover you can always add more but I found that 2 ½ cups was perfect for me.
- I browned the sausage on the stovetop while my spaghetti was cooking in the Instant Pot. Alternatively you can use the sauté setting on the Instant Pot to brown the sausage before pressure cooking the spaghetti and then set it aside until later. Just make sure to wipe out the pot so that nothing is sticking to the bottom.

Would this work with whole wheat spaghetti?
yep! Same cooking time, same amount.
What if you don’t have the air fryer lid is there another substitute or best just to put in the oven.
Hi Mary, I would use the oven
I love your recipes but this one didn’t do as much for me. I made a couple cooking mistakes (Blame my cat!) and wonder if that’s why. My pasta stuck to the bottom and there just wasn’t much overall flavor. I followed your instructions up until the baking section except my sealing valve was not down tight and I think it released some liquid before sealing. My other mistake was mixing the spaghetti sauce in with the other ingredients before using the air fryer lid instead of pouring it on top of the sausage. I layered the sausage and cheese on top and baked it with the air fryer lid. First time using the bake cycle! When I reheated leftovers, I added some more Italian seasoning. I would have added more ricotta, if I’d had any left. Do you think my cooking errors made the change in results? (BTW, my cat stole some of the uncooked pasta and then tried to check out what was in the open pot when I was trying to refer to the instructions. That’s why I blame him! 🙀)
Lol! Sorry about the mishaps! It may have been why?? But more ricotta sounds like a great addition for next time
Delicious! Finally bought the Air Fryer lid for my Instant pot, so this was another 1 pot meal for us.

Nice! I hope you like it!
I made this tonight as I am trying to find recipes that my picky kid would eat. After tasting it, I was torn between having him like it and also not liking it so that there would be more for me!
It was a win-win, we both love it.
Thanks Karen!
lol! That’s so great! I’m glad you liked it 🙂
Made this for Sunday lunch—it was amazing!

I agree! We really loved it! thanks for the 5 stars Laura!
