Equipment

  • Large skillet or sauté pan
  • Wooden spoon or spatula
  • Cutting board
  • Chef’s knife
  • Measuring cups and spoons
  • 9×13 baking dish
  • Mixing spoon or ladle
  • Oven mitts
  • Aluminum foil (optional, for covering if needed)

Ingredients

Pasta + Sausage Base

  • 1 lb mild or hot Italian sausage casings removed if linked
  • 1 tbsp olive oil if needed
  • 1 small onion diced
  • 3–4 garlic cloves minced
  • 1 jar 24 oz marinara sauce
  • 1 cup heavy cream or half-and-half
  • ½ cup chicken broth
  • 1 tsp Italian seasoning
  • ½ tsp red pepper flakes optional
  • Salt & pepper to taste
  • 20 oz fresh cheese tortellini

Cheese Topping

  • 1 ½ cups shredded mozzarella
  • ½ cup shredded parmesan
  • Optional: ½ cup ricotta or mascarpone dolloped on top

Fresh Add-Ons (Optional)

  • Fresh basil
  • Parsley
  • A drizzle of pesto

Instructions

Cook the Sausage

  • Heat a large skillet over medium-high heat.
  • Add Italian sausage and break it apart as it cooks.
  • Add onion and sauté until softened (3–4 minutes).
  • Stir in garlic and cook 1 minute more.

Make the Sauce

  • Add marinara sauce, heavy cream, chicken broth, Italian seasoning, red pepper flakes, salt, and pepper.
  • Simmer 5 minutes to thicken slightly.
  • Add the fresh tortellini straight into the sauce.
  • Simmer 3–4 minutes until tortellini starts to soften (it will finish cooking in the oven).

Assemble the Bake

  • Pour everything into a greased 9×13 baking dish.
  • Sprinkle mozzarella + parmesan over the top.
  • (Optional) Dot ricotta/mascarpone over the surface for extra creaminess.

Bake

  • Bake at 375°F for 18–22 minutes, or until bubbling and golden.
  • Broil the top for 1–2 minutes if you want extra browning.

Serve

  • Let rest for 5 minutes, then top with:
  • 🌿 Fresh basil
  • 🌿 Parsley
  • ✨ A spoonful of pesto (optional)
  • Serve warm!

Notes

  • Use fresh tortellini for best texture: Fresh or refrigerated tortellini cook quickly and absorb the sauce well. If using frozen, thaw first or increase simmering time by 2–3 minutes.
  • Brown the sausage deeply: Letting the sausage develop color adds richer flavor and caramelization to the sauce.
  • Choose your heat level: Mild sausage keeps the dish kid-friendly, while hot Italian sausage adds a delicious spicy kick.
  • Cream options: Heavy cream makes the sauce extra rich, while half-and-half provides a lighter but still creamy texture.
  • Don’t overcook the tortellini on the stovetop: It should be slightly underdone before baking—it finishes cooking in the oven.
  • Add spinach for extra greens: Stir 2–3 cups of fresh baby spinach into the hot sauce before adding the tortellini.
  • Ricotta or mascarpone = creamier bake: Dollop on top before adding cheese for a lasagna-like texture.
  • Cheese variations: Mozzarella melts beautifully, but provolone or Italian cheese blends work great too.
  • Prevent over-browning: If the top browns too quickly, loosely cover the baking dish with foil for the last 10 minutes.
  • Make-ahead tip: Assemble the dish up to 24 hours in advance and refrigerate—just add 8–10 minutes to the bake time.
  • Leftovers reheat well: Add a splash of cream or broth when reheating to keep the sauce silky.

⭐ Flavor Notes

  • The cream + marinara makes a dreamy, pink, ultra-creamy sauce.
  • Tortellini cooks in the sauce, absorbing tons of flavor.
  • Using hot Italian sausage adds a spicy, savory depth.
  • The cheese topping melts into an irresistible bubbly crust.

🔧 Optional Add-Ins

  • Spinach (stir into the hot sauce)
  • Mushrooms (sauté with onion)
  • Sun-dried tomatoes
  • Bell peppers
  • A layer of ricotta under the cheese for a lasagna-style effect
