Costco Tortellini Recipe: Cheese-Filled Pockets in Creamy Sauce

There’s a reason Costco’s cheese tortellini has a cult following—it transforms a simple weeknight dinner into something special. This recipe builds on that foundation with a creamy sauce that complements the rich, cheesy filling perfectly.

I developed this method to highlight the tortellini’s quality while adding layers of flavor through a velvety sauce and complementary ingredients. The process is straightforward, with precise timing to ensure the pasta stays tender and the sauce reaches the ideal consistency.

What emerges is a dish where each bite delivers the soft, cheese-filled pasta swimming in a creamy, perfectly seasoned sauce. The result feels restaurant-worthy but comes together with minimal effort in your own kitchen.

Serve as a main course or as part of a larger meal. Here’s how to make it.

Ingredients for Costco Tortellini

Transform Costco’s beloved tortellini with a silky sauce and vibrant accompaniments for a dish that feels luxurious yet simple.

The tortellini is the star—Costco’s cheese-filled version is consistently excellent, found in the refrigerated section. For the sauce, heavy cream and Parmesan from a wedge (not pre-grated) ensure a velvety texture. Shallots add subtle sweetness; Whole Foods often has them loose, making it easy to grab just one. The white wine should be dry—Trader Joe’s Charles Shaw Pinot Grigio is a reliable, affordable option.

No white wine? Substitute with additional vegetable stock and a splash of lemon juice. Fresh spinach can be swapped for baby kale or arugula—just wilt briefly. For a richer sauce, replace half the cream with whole milk. The nutmeg is subtle but key; if you don’t have whole, pre-ground works at the same amount. Skip the flour for a gluten-free version—the sauce will still cling beautifully.

The tortellini cooks in minutes, so prep everything else first. Leftovers keep 3-4 days refrigerated, though the pasta may absorb some sauce. Reheat gently with a splash of cream or water. For freezing, undercook the tortellini slightly and store sauce separately for up to 3 months.

Step-by-Step Instructions for Cheese-Filled Tortellini in Creamy Sauce

Master the technique for a velvety sauce that clings perfectly to each cheese-filled pocket.

Step 1: Sauté Aromatics to Build Flavor Base

Heat the 1 tbsp Extra-Virgin Olive Oil in a large skillet over medium heat. Add the finely diced shallot and cook for 3-4 minutes until translucent and just beginning to caramelize at the edges. This develops the sweet, mild onion foundation for your sauce.

Add the 4 cloves minced garlic cloves and cook for 30 seconds, stirring constantly, until fragrant but not browned. I keep the heat moderate here—burnt garlic turns bitter and ruins the sauce. The aroma should be rich and inviting, not acrid.

Step 2: Deglaze and Create the Sauce Foundation

Pour in the 0.5 cup white wine and 0.5 cup vegetable stock, using a wooden spoon to scrape up any browned bits from the pan bottom. Simmer for 4-5 minutes until the liquid reduces by about half. This deglazing step captures all the concentrated flavor from the sautéed aromatics.

Sprinkle in the 1 tbsp all-purpose flour and whisk vigorously for 1 minute to create a smooth roux. Then add the 0.5 cup unsalted butter, whisking until fully melted and incorporated. The mixture should be glossy and slightly thickened at this stage.

Step 3: Build the Creamy Sauce with Depth

Slowly pour in the 1.5 cups heavy cream while whisking constantly to prevent curdling. Bring to a gentle simmer and cook for 3-4 minutes until the sauce thickens enough to coat the back of a spoon. The color should deepen slightly, and the texture should be rich and velvety.

Stir in the 1 tsp kosher salt, 0.5 tsp freshly ground black pepper, and 0.25 tsp nutmeg. I always use freshly grated nutmeg—it has a brightness that pre-ground versions lack. Taste and adjust seasoning if needed, but remember the parmesan will add saltiness later.

Step 4: Cook Tortellini and Finish the Sauce

While the sauce simmers, cook the 20 oz Costco Cheese Tortellini according to package instructions in salted boiling water until al dente (they’ll finish cooking in the sauce). Reserve ½ cup of pasta water before draining. This starchy water helps adjust the sauce consistency.

Add the drained tortellini to the sauce along with the 4 cups fresh spinach. Fold everything together gently for 1-2 minutes until the spinach wilts and the tortellini are fully coated. If the sauce is too thick, add reserved pasta water 1 tablespoon at a time until it reaches the perfect creamy consistency.

Step 5: Add Parmesan and Serve Immediately

Remove the pan from heat and stir in the 0.75 cup parmesan cheese until fully melted and the sauce becomes luxuriously smooth. The parmesan adds depth and a subtle sharpness that balances the richness of the cream.

Serve immediately while hot, as the sauce will thicken as it cools. Each portion should have a generous amount of sauce clinging to the tortellini, with visible flecks of spinach throughout. Garnish with additional parmesan if desired, though the sauce is already perfectly seasoned from the cheese added during cooking.

Wine and Beer Pairings for costco tortellini

Crisp White Wines

I love pairing this dish with a dry Pinot Grigio from Northern Italy—its bright acidity cuts through the creaminess beautifully. Santa Margherita Pinot Grigio is a reliable choice that won’t overpower the delicate flavors of the tortellini. 🍷

Rich Italian Whites

A Gavi di Gavi offers a richer white wine option with mineral notes that complement the Parmesan. For a budget-friendly pick, try Barefoot Pinot Grigio—it’s widely available and balances the dish’s richness.

Light Red Options

If you prefer red wine, go for a light-bodied Pinot Noir like Meiomi. Its subtle earthiness pairs well without overwhelming the creamy sauce. Serve slightly chilled for best results.

Beer Pairings

A crisp Italian lager like Peroni cleanses your palate with its effervescence. For craft lovers, a Belgian witbier with citrus notes adds a refreshing contrast to the richness. 🍺

Sparkling Choices

Prosecco is my favorite for celebrations—its bubbles and slight sweetness balance the creamy sauce. La Marca Prosecco is a crowd-pleaser that won’t break the bank.

Non-Alcoholic Pairings

Sparkling water with a lemon wedge mimics wine’s acidity. For a cozy option, try hot herbal tea with a hint of honey to complement the dish’s warmth.
