What Makes This Chicken Spaghetti Different?
Traditional chicken spaghetti recipes often call for processed cheese products. While there's nothing wrong with that, I prefer the flavor and texture of freshly grated cheese.
Freshly grated cheese melts smoother and creates a richer sauce. It also allows you to control the flavor profile by choosing your favorite cheese blend.
Another difference is the pasta. Instead of traditional spaghetti, I often use Pete's Pasta. It has become my favorite option when I want a lower-carb, higher-protein meal. The texture holds up beautifully, and it doesn't taste like a compromise.
Ingredients You'll Need
This easy chicken spaghetti recipe uses simple ingredients that you may already have on hand.
- Chicken breasts
- Cream of chicken soup
- Rotel tomatoes
- Better Than Bouillon chicken base
- Water
- Dried onion
- Garlic powder

- High-protein pasta, such as Pete's Pasta

Ingredient Tips
Use Freshly Grated Cheese
Skip the pre-shredded cheese if possible.
Packaged shredded cheese contains anti-caking agents that can prevent smooth melting. Grating your own cheese creates a much creamier sauce.
Choose a Good High-Protein Pasta
If you're trying to add more protein to your meals, Pete's Pasta is a fantastic choice. It has become my go-to for recipes like this because the texture stays firm and the flavor is excellent.
Many protein pastas can become mushy during cooking. This one holds up remarkably well.
Rotel Adds Flavor
The Rotel tomatoes bring a little acidity, a little heat, and plenty of flavor. If your family prefers milder dishes, you can use the mild version.
