Boil the Pasta: In a large pot, bring salted water to a rolling boil. Add pasta and cook until al dente, about 10-12 minutes. Drain and keep warm.

Cook the Bacon: In a skillet, add chopped bacon and cook until crispy, about 6-8 minutes. Drain on paper towels.

Sauté the Beef: Increase skillet heat and add ground beef, seasoning with salt and pepper. Cook until browned, about 5-7 minutes. Set aside with bacon.

Sauté Aromatics: In the same skillet, lower the heat and add onion and garlic. Sauté until onion is translucent, about 3-4 minutes.

Create the Sauce: Reduce heat and stir in heavy cream, beef broth, and Worcestershire sauce. Simmer for 5 minutes until thickened.

Add Cheeses: Whisk in cheddar and Parmesan cheeses until melted and creamy. Adjust consistency with broth or cream if needed.

Combine Everything: Toss pasta, beef, and bacon into the sauce. Mix until well-coated and warmed through, about 2-3 minutes.

Serve and Garnish: Serve hot, garnish with parsley and jalapeños if desired.
