The Complete Shopping Rundown
- 12 ounce package egg noodles – gotta have those tender noodles that soak up all the sauce.
- 2 (10.5 ounce) cans condensed cream of mushroom soup – the creaminess that holds everything together.
- 2 cups shredded Cheddar cheese, divided – one part mixed in and one for topping, gotta have that melty cheesy goodness everywhere.
- 2 (5 ounce) cans tuna, drained – flaky and protein-packed, the star of this casserole.
- 1 cup frozen green peas – just the right pop of sweetness and color.
- ½ (4.5 ounce) can sliced mushrooms – adds a deep, earthy flavor.
- ¼ cup chopped onion – for that sharp bite sneaking through.
- 1 cup crushed potato chips – don’t sleep on this crunchy topping, it takes it up a notch.
Walking Through Every Single Move
- First off, you gotta preheat your oven to 350 degrees F. Pressure cooker gets us far, but that last bake finishes the top perfectly.
- Next, bring a big pot of salted water to a boil to cook your egg noodles until they’re tender but still got that bite, about 8 minutes. Then drain them good.
- Now grab your pressure cooker’s pot. Mix together cream of mushroom soup, 1 ½ cups of shredded Cheddar cheese, tuna, green peas, sliced mushrooms, and chopped onion until it’s all combined and kinda thick.
- Stir in those cooked egg noodles gently so everything blends without breaking up the noodles too much.
- Dump it all into a greased 9x13 inch baking dish. Spread it out nice and even so every bite’s got a bit of everything.
- Layer on the remaining ½ cup of Cheddar cheese and then sprinkle the crushed potato chips on top for that crispy crust.
- Pop the dish in the preheated oven and bake it until you see bubbles and melted cheese, about 25 to 30 minutes. Let it cool a bit before you serve so it kinda sets up nice.
