Why You’ll Love This Recipe

This recipe is perfect for busy weeknights because it’s quick, satisfying, and easy to customize. The brown butter brings a rich, caramelized flavor that pairs beautifully with the savory sausage, while kale adds freshness and balances the richness of the dish.

Best of all, most of the cooking happens in a single skillet, making cleanup just as easy as preparation.

Ingredients

• 20 ounces cheese tortellini (fresh or refrigerated)
• 1 pound Italian sausage (mild or spicy), casings removed
• 6 tablespoons unsalted butter
• 3 cloves garlic, minced
• 4 cups chopped kale, stems removed
• ½ cup freshly grated Parmesan cheese
• 1 teaspoon chopped fresh sage (optional)
• ¼ teaspoon red pepper flakes (optional)
• Salt and freshly ground black pepper, to taste
• 2–3 tablespoons reserved pasta water
• Fresh lemon juice (optional)

Instructions

Bring a large pot of salted water to a boil and cook the tortellini according to the package directions until just al dente. Before draining, reserve a few tablespoons of the pasta water.

While the tortellini cooks, heat a large skillet over medium heat. Add the sausage and cook, breaking it into bite-sized pieces, until browned and fully cooked. Transfer the sausage to a plate, leaving about a tablespoon of the drippings in the pan.

Add the butter to the skillet. Allow it to melt, then continue cooking, stirring frequently, until it begins to foam and turns golden brown. You’ll notice a rich, nutty aroma and brown specks forming on the bottom of the pan. Watch carefully, as brown butter can burn quickly.

Stir in the garlic and sage, if using, and cook for about 30 seconds until fragrant. Add the kale and cook for 2 to 3 minutes until it wilts.

Return the cooked sausage to the skillet, then add the drained tortellini. Toss everything together, adding a splash of the reserved pasta water if needed to create a silky sauce.

Stir in the Parmesan cheese and season with salt, black pepper, and red pepper flakes if desired. Finish with a squeeze of fresh lemon juice for brightness and serve immediately with extra Parmesan on top.

Tips for Success

The key to this recipe is properly browning the butter. Cook it slowly over medium heat and keep stirring so the milk solids toast evenly without burning.

Avoid overcooking the tortellini, as it will continue to cook slightly when tossed with the hot sauce. Freshly grated Parmesan also melts more smoothly than pre-shredded cheese and gives the sauce a richer flavor.

If the sauce seems too thick, simply add another splash of reserved pasta water until it reaches your desired consistency.

Easy Variations

This recipe is easy to adapt based on what you have on hand.

• Substitute spinach for kale if you prefer a milder green.
• Use chicken sausage or turkey sausage for a lighter version.
• Add sliced mushrooms for extra earthy flavor.
• Stir in a splash of heavy cream for a creamier sauce.
• Sprinkle toasted walnuts or pine nuts over the finished dish for added crunch.
• Make it vegetarian by replacing the sausage with sautéed mushrooms or plant-based sausage.

What to Serve With It

Brown Butter Tortellini with Sausage and Kale is satisfying on its own, but it also pairs well with a few simple sides. Garlic bread is perfect for soaking up the buttery sauce, while a crisp green salad with a light vinaigrette balances the richness of the pasta. Roasted asparagus, broccoli, or Brussels sprouts also make excellent accompaniments.

Storing Leftovers

Store leftovers in an airtight container in the refrigerator for up to three days.

To reheat, warm the pasta gently in a skillet over medium-low heat with a splash of water or chicken broth to loosen the sauce. You can also microwave individual portions in short intervals, stirring between each until heated through.
