Why you’ll love this recipe

It’s fast. It’s forgiving. It highlights the tortellini without burying it in heavy cream—yet the butter and broth make a sauce that clings to every fold. The garlic and dried basil provide aromatic depth while the Parmesan adds a salty, nutty finish. This makes a perfect solo dinner, a cozy meal for two, or an easy plate to share without a lot of hands-on time.

Ingredients

• 32 ounces chicken broth or vegetable broth, divided (see note 1)
• 2 tablespoons cornstarch (see note 2)
• 1 (16 ounce) package frozen cheese tortellini (see note 3)
• 4 tablespoons butter (see note 4)
• 2 cloves garlic, minced
• 2 teaspoons dried basil
• 1/4 cup freshly grated Parmesan cheese for garnish
• Fresh basil chiffonade, for garnish, optional

Notes on ingredients

Note 1: Use broth that matches your dietary preferences and the flavor you enjoy—either chicken broth or vegetable broth will make a flavorful base. Keep 32 ounces total and divide it as called for in the steps below.

Note 2: Cornstarch is the thickening agent that gives the sauce a glossy, clingy texture without dairy-heavy cream. Measure it carefully so the sauce reaches the right consistency.

Note 3: Frozen cheese tortellini cooks quickly from frozen and holds its shape in the sauce. No need to thaw; add it straight from the package.

Note 4: Butter is the flavor backbone here; four tablespoons give richness that balances the broth and garlic. If you prefer a plant-based option, substitute an equal amount of a neutral plant-based spread.

Equipment

• A medium-large skillet or sauté pan with a lid
• A measuring cup and spoons
• A small bowl or cup for whisking the cornstarch
• Tongs or a slotted spoon
• Microplane or grater for the Parmesan

Step-by-step directions

This section rewrites the original directions into clear, step-by-step instructions that follow the ingredient list exactly and maintain the original order of actions.

1. Prepare the cornstarch slurry.

   Measure 2 tablespoons cornstarch into a small bowl. Add 1/4 cup of the reserved broth (from the 32 ounces) and whisk until completely smooth with no lumps. Set the slurry aside near the stove so it’s ready when the sauce needs thickening.

2. Bring the broth to a simmer.

   Place a medium-large skillet over medium-high heat and pour in 3 3/4 cups (30 ounces) of the chicken or vegetable broth, reserving the 1/4 cup you used for the slurry. Heat the broth just until it gently simmers—small bubbles should break at the surface—but do not boil vigorously.

3. Cook the frozen tortellini in the simmering broth.

   Add the entire 16-ounce package of frozen cheese tortellini directly into the simmering broth. Stir gently to separate the pieces so they don’t stick together. Let the tortellini cook in the simmering broth according to the package directions—typically 4 to 6 minutes—until they are tender and cooked through. Test one to confirm it is heated all the way through and tender in the center.

4. Reduce heat and add butter.

   When the tortellini is cooked, lower the heat to medium-low. Add 4 tablespoons butter to the skillet and swirl or stir gently until the butter melts and begins to emulsify with the broth. This creates the buttery base of the sauce.

5. Saute the garlic and add dried basil.

   Push the tortellini slightly aside and add the 2 cloves minced garlic to the melted butter. Cook the garlic just until fragrant—about 30 to 45 seconds—stirring so it does not brown. Sprinkle in 2 teaspoons dried basil and stir to distribute the herb through the sauce. Keep the heat on medium-low so the garlic softens without burning.

6. Thicken the sauce with the cornstarch slurry.

   Give the cornstarch slurry a quick whisk to recombine, then very slowly pour it into the skillet while stirring the sauce. Continue stirring for 1 to 2 minutes as the sauce thickens and becomes glossy. If the sauce seems too thin, you can let it simmer gently another minute; if it becomes too thick, stir in a tablespoon or two of extra broth to loosen it. The goal is a velvety sauce that coats each tortellini.

7. Finish and plate.

   Remove the skillet from the heat. Taste a tortellini and adjust seasoning if needed—if you like, add a pinch of salt and a grind of black pepper. Divide the tortellini among bowls or plates, spooning the garlic butter sauce over the top.

8. Garnish and serve.

   Sprinkle each serving with about 1 to 2 tablespoons of freshly grated Parmesan cheese (for a total of 1/4 cup across servings) and add fresh basil chiffonade if desired for color and a bright herbal note. Serve immediately while warm.

Troubleshooting and tips

• Sauce too thin: Whisk another 1/2 teaspoon cornstarch with 1 tablespoon cold broth and stir it into the simmering sauce, cooking until it thickens. Add slowly—the sauce will thicken quickly.
• Sauce too thick: Stir in small amounts of additional broth (1 tablespoon at a time) until you reach the desired consistency.
• Garlic caution: Minced garlic browns and turns bitter quickly. Keep the heat moderate and stir constantly when cooking garlic in butter.
• Cheese tortellini choices: Use a high-quality frozen cheese tortellini for best texture and flavor; fresh tortellini will work but will cook in a shorter time so adjust accordingly.

Make-ahead and storage

You can prepare the sauce and cook the tortellini separately, then combine them just before serving. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat with a splash of broth to refresh the sauce—avoid high heat which can break the sauce’s emulsion and make the butter separate.

Serving suggestions

This dish stands on its own, but a few simple sides round it out beautifully:

• A crisp green salad with a lemon vinaigrette to cut through the richness.
• Steamed or roasted seasonal vegetables—broccolini, asparagus, or a medley of roasted cherry tomatoes.
• Garlic bread or a slice of crusty baguette to soak up the sauce.

Flavor variations

• Extra vegetables: Stir in a cup of fresh spinach or a cup of peas in the last minute of cooking so they wilt and heat through without adding moisture that dilutes the sauce.
• Spicy kick: Add a pinch of red pepper flakes when you cook the garlic for subtle heat.
• Herb swap: If you have fresh herbs, swap the dried basil for 1 tablespoon chopped fresh basil added just before serving for a brighter flavor.

Why the technique matters

Cooking the tortellini directly in the broth infuses each piece with subtle savory flavor while conserving pot space and time. Emulsifying the melted butter into the broth and thickening slightly with cornstarch creates a silky, clingy sauce without using heavy cream. Finishing with fresh Parmesan and optional basil adds depth, salt, and aromatic lift.

Final thoughts

Simple ingredients and gentle technique yield a dish that tastes like you spent far more time on it than you did. This Cheese Tortellini in Garlic Butter Sauce is adaptable, quick, and deeply comforting—the kind of recipe you’ll return to when you want maximum flavor with minimum fuss.
