If comfort food had a personality, One Pot Cowboy Spaghetti would be bold, messy, unapologetically cheesy, and deeply satisfying. This is the kind of dinner that fills the kitchen with rich aromas, brings everyone to the table fast, and leaves behind empty plates and happy sighs. It’s rustic, hearty, and designed for real life — busy nights, hungry families, and anyone who wants maximum flavor with minimal cleanup.

Cowboy spaghetti takes everything we love about classic spaghetti and turns it up a notch. Think seasoned ground beef, smoky spices, tender pasta cooked directly in a savory tomato-based sauce, and plenty of melted cheese tying it all together. And the best part? Everything cooks in one pot. No boiling pasta separately. No extra pans. No sink full of dishes.

This one-pot spaghetti recipe is inspired by hearty American comfort cooking — the kind you’d imagine simmering over a campfire or bubbling away on a ranch stove after a long day. It’s filling, flexible, and endlessly customizable, which makes it perfect for weeknight dinners, casual gatherings, or even meal prep.

Let’s dig into why this dish works so well, how to make it perfectly every time, and all the ways you can make it your own.

Ingredients for One Pot Cowboy Spaghetti

Use these simple, easy-to-find ingredients to create big flavor with minimal effort:

1 lb ground beef
1 tablespoon olive oil
1 small onion, diced
3 cloves garlic, minced
1 teaspoon smoked paprika
1 teaspoon chili powder
½ teaspoon cumin
½ teaspoon black pepper
1 teaspoon salt (adjust to taste)
1 tablespoon tomato paste
1 can (14.5 oz) diced tomatoes
3 cups beef broth
1 cup tomato sauce
8 oz uncooked spaghetti, broken in half
1½ cups shredded cheddar cheese
½ cup shredded mozzarella cheese
Fresh parsley or green onions for garnish (optional)

Instructions

Heat olive oil in a large pot or deep skillet over medium heat.
Add ground beef and cook until browned, breaking it apart as it cooks. Drain excess grease if needed.
Add diced onion and cook for 2–3 minutes until softened.
Stir in garlic, smoked paprika, chili powder, cumin, salt, and black pepper. Cook for 30 seconds until fragrant.
Mix in tomato paste, diced tomatoes, tomato sauce, and beef broth. Stir well to combine.
Add the uncooked spaghetti, pressing it gently into the liquid so it’s mostly submerged.
Bring to a gentle boil, then reduce heat to medium-low. Cover and simmer for 12–15 minutes, stirring occasionally, until pasta is tender and sauce thickens.
Remove from heat and stir in cheddar and mozzarella cheese until melted and creamy.
Taste and adjust seasoning if needed.
Garnish with fresh parsley or green onions and serve hot.

What Makes Cowboy Spaghetti Different?

Unlike traditional spaghetti, cowboy spaghetti is richer, bolder, and more rustic. The pasta cooks directly in the sauce, absorbing every bit of flavor from the beef, spices, and tomatoes. The result is thicker, heartier, and far more satisfying than standard spaghetti with sauce poured on top.

It’s also incredibly forgiving — perfect for cooks of all skill levels.

Pro Tips for the Best One Pot Spaghetti

Stir occasionally to prevent sticking, especially in the first few minutes
Break the spaghetti so it fits evenly and cooks uniformly
Don’t rush the simmer — gentle heat ensures tender pasta and thick sauce
Add cheese off heat so it melts smoothly without separating

Easy Variations to Try

Spicy Cowboy Spaghetti: Add diced jalapeños or a pinch of cayenne
Creamy Version: Stir in ¼ cup heavy cream before adding cheese
Tex-Mex Twist: Add black beans and corn, top with pepper jack cheese
Turkey Cowboy Spaghetti: Swap ground beef for ground turkey

Serving Suggestions

Serve this dish with:

Garlic bread or crusty bread
Simple green salad
Roasted vegetables
Pickles or coleslaw for contrast

It’s filling enough to stand alone, but sides make it feel like a full feast.

Storage & Reheating

Refrigerate: Store in an airtight container for up to 4 days
Reheat: Warm gently on the stove or microwave with a splash of broth
Freeze: Freeze for up to 2 months (cheese texture may soften slightly)
