1-Step 1: Cook the Tortellini In a pot, bring 2.5 cups of broth to a boil. Add the cheese tortellini and cook until they float to the top, about 3 minutes, or until they reach an internal temperature of 165 degrees. Once done, drain them completely to remove excess liquid.

2-Step 2: Prepare the Sauce Base In a small bowl, whisk the remaining 1.5 cups of broth with the cornstarch. This mixture will thicken your sauce nicely, so stir it well for a smooth texture.

3-Step 3: Make the Garlic Butter Sauce In a large non-stick skillet, melt the butter over medium-high heat until it starts foaming. Stir in the minced garlic and dried basil, and cook for 2 minutes to release their flavors.

4-Step 4: Combine and Simmer Add the broth-cornstarch mixture to the skillet and bring it to a boil. Let it simmer until thickened, about 2 minutes, for a creamy consistency.

5-Step 5: Mix and Serve Add the cooked cheese tortellini to the skillet and toss to coat with the sauce. Serve immediately, garnished with the Parmesan cheese and fresh basil if desired. This step ensures every bite of cheese tortellini is full of flavor.
