8 oz medium pasta shells
1 tablespoon olive oil
1 pound ground beef
1 small sweet onion, diced
5 cloves garlic, minced
1 teaspoon Italian seasoning
1 teaspoon dried parsley
½ teaspoon dried oregano
½ teaspoon smoked paprika
2 tablespoons all-purpose flour
1 cup beef stock
1 (15 oz) can marinara sauce
¾ cup heavy cream
¼ cup sour cream
Kosher salt and freshly ground black pepper, to taste
1½ cups freshly grated cheddar cheese
Cook the pasta shells according to package instructions in a large pot of salted boiling water. Drain and set aside.
Heat olive oil in a large skillet over medium-high heat. Add the ground beef and cook for 3–5 minutes, breaking it up, until browned. Drain excess fat and remove beef from the skillet.
In the same skillet, add the diced onion and cook for about 2 minutes, stirring frequently. Add the garlic and cook for 1 minute until fragrant.
Sprinkle in the flour and whisk constantly for about 1 minute until lightly browned.
Gradually whisk in the beef stock until smooth. Stir in the marinara sauce, Italian seasoning, parsley, oregano, and smoked paprika.
Bring to a boil, then reduce heat and simmer for 6–8 minutes, stirring occasionally, until slightly thickened.
Stir in the cooked pasta and return the beef to the skillet.
Add the heavy cream and cook for 1–2 minutes until heated through. Season with salt and pepper to taste.
Stir in the sour cream until fully combined.
Fold in the cheddar cheese and cook for 1–2 minutes until melted and creamy.
Serve immediately, garnished with extra parsley if desired.
Use freshly grated cheese for smoother melting and better texture.
Don’t overcook the pasta—slightly al dente works best in creamy sauces.
Swap ground beef for ground turkey or chicken for a lighter version.
Add heat with red pepper flakes if you like a little spice.
Great leftovers: Reheat gently with a splash of milk or cream
