This creamy beef and shells is the ultimate one pot pasta! Tender pasta shells simmer in marinara and water (or beef broth for extra flavor), then get swirled with heavy cream for a rich, hearty, and family-friendly dinner. Ready in just 30 minutes, it’s the perfect cozy weeknight meal.

Ingredients

Scale

  • 1 lb ground beef

  • 1 medium onion, diced

  • 3 cloves garlic, minced

  • 1 teaspoon Italian seasoning

  • 3 cups marinara sauce (store-bought or homemade)

  • 3 cups water (or substitute beef broth for more flavor)

  • 12 oz medium pasta shells (uncooked)

  • 1 cup heavy cream

  • Salt and pepper, to taste

  • Fresh parsley, chopped (for garnish)

Instructions

  • In a large pot or deep skillet, cook the ground beef and diced onion over medium heat until the beef is browned and the onion is softened. Drain excess grease if necessary.

  • Stir in garlic and Italian seasoning. Cook for 1–2 minutes until fragrant.

  • Add marinara sauce and water (or beef broth). Stir well and bring to a gentle simmer.

  • Stir in the uncooked pasta shells. Cover and cook, stirring occasionally, until the pasta is tender and most of the liquid is absorbed (about 12–14 minutes).

  • Reduce heat to low and stir in heavy cream  until melted and creamy. Season with salt and pepper to taste.

  • Garnish with fresh parsley and serve warm.

Notes

  • Broth option: Water works great, but beef broth will deepen the flavor.

  • Veggie boost: Stir in spinach, mushrooms, or peas for extra nutrition.

  • Make-ahead: Store leftovers in the fridge for 3–4 days. Add a splash of cream or broth when reheating to keep the sauce creamy.

  • Freezer-friendly: Freeze in a sealed container for up to 2 months. Slightly undercook the pasta before freezing so it reheats better.
