Instructions
Cook the Bacon:
In a large skillet or Dutch oven, cook the chopped bacon over medium heat until crispy. Remove the bacon with a slotted spoon and set aside on paper towels to drain. Leave the bacon grease in the pan.
Brown the Ground Beef:
Increase the heat to medium-high. Add the ground beef to the skillet with the bacon grease. Cook, breaking it apart with a spoon, until browned and no longer pink. Drain excess fat if necessary.
Sauté the Vegetables:
Reduce the heat to medium. Add the diced onion, minced garlic, and diced green bell pepper (if using) to the skillet. Sauté until the vegetables are soft and fragrant, about 5 minutes.
Add the Sauces:
Stir in the diced tomatoes (with juice), tomato sauce, barbecue sauce, Worcestershire sauce, and red pepper flakes. Season with salt and pepper to taste. Bring the mixture to a simmer.
Combine with Spaghetti:
Add the cooked spaghetti to the sauce, tossing to combine. Let it simmer for a few more minutes so the spaghetti absorbs some of the sauce flavors.
Add Bacon and Cheese:
Stir in the cooked bacon. Sprinkle the shredded cheddar cheese over the top of the spaghetti and cover the skillet with a lid. Let it sit on low heat until the cheese is melted, about 3-5 minutes.
Serve:
Serve the Cowboy Spaghetti hot, garnished with sliced green onions on top.
