What Ingredients are in One Pot Chicken Spaghetti?
One of the best things about this chicken spaghetti recipe is how it transforms simple ingredients into something that tastes like you’ve been cooking all day. The combination of tender chicken, earthy mushrooms, and vibrant peppers creates a dish that’s comforting yet full of fresh flavors.
And honestly, who doesn’t appreciate a recipe where you can toss everything in one pot and walk away? The ingredient list is straightforward, focusing on items most of us already have tucked away in our pantry or fridge.
- 4-5 boneless skinless chicken breasts
- 2 cups fresh mushrooms
- 1 cup green pepper
- 1½ cups onions
- 2 tablespoons minced garlic
- 3 tablespoons oregano
- 1 tablespoon sugar
- 2-3 cups thick and zesty pasta sauce
- Spaghetti noodles (though not mentioned in the knowledge base)
When shopping for these ingredients, quality matters, especially for the pasta sauce since it forms the base of your flavor profile. I like to look for sauces labeled “thick and zesty” as mentioned, but you could certainly use your family’s favorite brand.
For the mushrooms, white button varieties work perfectly, but feel free to mix in some cremini for deeper flavor. And while the recipe doesn’t specify, you’ll obviously need spaghetti noodles—about a pound should work for this amount of sauce and protein.
They’ll cook right in the same pot, absorbing all those wonderful flavors.
How to Make this One Pot Chicken Spaghetti

Making this chicken spaghetti couldn’t be simpler, which is exactly what we need on busy weeknights, right?
Start by prepping all your vegetables – slice 2 cups of fresh mushrooms, dice 1 cup of green pepper, and chop 1½ cups of onions into pieces that will cook down nicely. Next, cut your 4-5 boneless skinless chicken breasts into bite-sized chunks. This guarantees everything cooks evenly and makes the final dish easier to serve and eat.
Once everything is prepped, simply combine all ingredients in either a slow cooker or a deep pot. Add the chicken, vegetables, 2 tablespoons of minced garlic, 3 tablespoons of oregano, and 1 tablespoon of sugar.
Pour in 2-3 cups of thick and zesty pasta sauce, giving everything a good stir to make sure it’s well combined. If using a slow cooker, set it on low and let it simmer for 2-3 hours, allowing all those flavors to meld together beautifully. If you’re using a stovetop pot instead, maintain a gentle simmer over low heat, giving it an occasional stir to prevent sticking.
The magic of one-pot cooking means the longer it simmers, the more the flavors intensify and mingle.
For an even more versatile cooking experience, consider preparing this recipe using a premium indoor grill that offers precise temperature control and easy cleanup.
Though not mentioned in the original recipe, about 30 minutes before serving, you’ll want to add your spaghetti noodles right into the pot. Break them in half if needed to fit, and make sure they’re fully submerged in the liquid.
They’ll cook directly in the sauce, absorbing all that wonderful flavor while releasing starch that naturally thickens everything up. When the pasta reaches al dente perfection and the chicken is thoroughly cooked, your one-pot wonder is ready to serve.
And can we talk about the minimal cleanup? Just one pot to wash means more time enjoying dinner and less time scrubbing dishes. For more complex recipes that require thorough mixing, a KitchenAid mixer would be an excellent addition to your kitchen arsenal.
