All the Pieces for This Meal
- 2 cups cooked chicken, shredded or chopped good and tender.
- 3 cups uncooked spaghetti, broken into two-inch pieces so it fits right inside the cooker.
- 2 cans cream of mushroom soup for that creamy base thats oh so rich.
- 3 cups grated sharp cheddar cheese, divided because you gotta have some on top to brown.
- ¼ cup finely diced green pepper for that subtle crunch and color pop.
- ¼ cup finely diced onion to add a mild sweetness and depth.
- 1 (4-oz.) jar diced pimentos, drained but ready to bring a little zing.
- 2 cups reserved chicken broth from cooking your chicken, thats where all the flavors at.
- Seasonings: 1 teaspoon Lawry's Seasoned Salt, a little cayenne pepper (⅛ to ¼ teaspoon depending on how spicy you like it), plus salt and pepper to taste.
The Exact Process From Start to Finish
First, you're gonna preheat your oven to 3509F (175deg;C) so it's ready when you need to bake. Meanwhile, get your spaghetti cooked in salted water until just al dente. Don't forget to save 2 cups of that chicken broth from the pot 60nt toss it, that liquid gold is your flavor bomb.
In a large bowl, mix your cooked chicken with the cooked spaghetti. Add in your cream of mushroom soup and 2 cups of that sharp cheddar cheese. Toss in the green pepper, onion, pimentos, and pour in the reserved chicken broth.
Now, sprinkle in the Lawry's Seasoned Salt and cayenne pepper. Give everything a good stir so it's all mixed up real good. Add salt and pepper to your liking but be careful cause that seasoned salt packs some punch.
Pour that cheesy chicken spaghetti mixture into a big baking dish and spread it out evenly. Sprinkle the remaining cup of shredded cheddar cheese on top, because you gotta have that melty top layer.
Bake it in the oven for 30 minutes or until you see it bubbly and lightly browned on top. The smell during this part is something else, y'all.
Once outta the oven, let it sit for about 5 minutes. This little rest helps it settle so when you scoop it, its not runny but perfect and creamy.
Time Savers That Actually Work
- Cook your chicken ahead or use leftover rotisserie chicken straight from the fridge.
- Break the spaghetti into two-inch pieces before cooking so it fits in your pressure cooker easily.
- Chop your veggies the night before and keep them in the fridge ready to toss in.
- Use pre-shredded cheese to skip that extra grating step.
- Reserve chicken broth while cooking the chicken so you dont waste time making broth separately.

The Flavor Experience Waiting for You
You remember that first spoonful melts in your mouth: creamy, cheesy, with the comforting texture of spaghetti soaking up all the goodness. The sharp cheddar has this boldness thats balanced by mellow mushroom soup and the slight kick from cayenne pepper.
When you bite in, you spot little pops of green pepper and mild sweet onion that add a fresh crunch. Then that hint of pimentos sneaks flavor in, brightening the dish with every mouthful.
Its that kinda dish where the cheesy top gets a little golden and crisp while inside stays rich and gooey. You just keep coming back for more; its warm, hearty, and exactly what your day needs.
Making It Last All Week Long
Store leftovers in an airtight container in the fridge and theyll keep for about 4 days. Just warm pieces up on the stove or microwave, and add a splash of broth if it looks dry.
If you wanna stash some for later, freeze portions in freezer-safe bags or containers. When ready to eat, thaw overnight in the fridge and reheat with a little extra liquid to keep it creamy.
For best results, dont freeze more than a couple weeks so that flavor stays fresh. Youll notice it still tastes pretty darn good and saves you from cooking on busy days.
Your Most Asked Questions Answered
- Can I use other pasta? Sure thing! Just pick shorter pasta shapes like penne or rotini that cook evenly under pressure.
- Do I have to pre-cook the chicken? Its best to have it cooked so it blends well without extra cooking time messing up your pasta texture.
- What if I dont like mushrooms? You can swap cream of mushroom soup for cream of chicken or celery soup, whatever you prefer.
- How do I know when quick release is safe? When pressure drops and the valve hiss stops, thats your cue to open the lid carefully.
- Can I make this spicy? Yup! Adjust cayenne pepper to your heat level or add a pinch of crushed red pepper flakes.
- What if my cheese doesnt melt smooth? Make sure you stir good when mixing ingredients and dont add cold cheese straight from fridge; let it sit a few minutes.
