Understanding Your Ingredients
Sirloin or ribeye steak provides the protein foundation for this dish. I always choose ribeye when I want extra marbling and flavor, while sirloin offers a leaner option.
Cheese tortellini adds comforting pasta texture that soaks up the cowboy butter beautifully. In my kitchen, I prefer fresh or refrigerated tortellini for the best texture and taste.
Unsalted butter forms the base of the cowboy butter sauce. Using unsalted allows you to control the salt level perfectly.
Fresh garlic cloves create aromatic depth that defines this dish. Minced fresh garlic makes all the difference compared to jarred versions.
Dijon mustard adds tangy complexity to the cowboy butter. Just one teaspoon provides the right amount of depth.
Fresh lemon juice brightens all the flavors with its acidity. I’ve learned that fresh-squeezed lemon tastes noticeably better than bottled.
Fresh parsley and chives contribute herbaceous freshness. These herbs should be added at the end to preserve their bright flavors.
The Method That Works
Step 1. Bring a large pot of salted water to a boil. Cook the tortellini according to package directions until tender but still firm to the bite. Reserve 1/2 cup of pasta water, then drain and set aside.
Step 2. Pat the steak pieces dry with paper towels. Season the steak with Cajun seasoning, smoked paprika, garlic powder, salt, and black pepper.
Step 3. Heat olive oil in your large skillet over medium-high heat. Sear the steak bites for 2-3 minutes per side until browned and cooked to your preferred level of doneness. Remove from the skillet and set aside to rest.
Step 4. Reduce heat to medium. Melt butter in the same skillet. Add minced garlic and cook until fragrant, about 1 minute. Stir in red pepper flakes, Dijon mustard, and lemon juice. Add parsley and chives, mixing well.
Step 5. Return the cooked tortellini and steak bites to the skillet. Toss until coated in the cowboy butter sauce. Add reserved pasta water as needed to create a silky sauce. Stir in Parmesan cheese until melted and creamy.
Step 6. Plate while hot. Garnish with extra Parmesan, freshly chopped parsley, and a sprinkle of Cajun seasoning. Serve immediately.
Making the Most of Leftovers
I typically store these one-pan cowboy butter tortellini steak bites in an airtight container in the refrigerator for up to 3 days. Keep the pasta and sauce together to maintain the best flavor.
For freezing, you can store steak bites and tortellini separately, though the texture changes slightly when frozen. Reheat slowly in a skillet for best results.
For the best texture, I reheat this dish gently in a skillet over medium-low heat, adding a little water or broth to revive the sauce’s creaminess. Avoid microwaving directly as it can make the steak tough.

Complete Your Meal
These one-pan cowboy butter tortellini steak bites pair beautifully with a crisp garden salad featuring mixed greens and tangy vinaigrette. Roasted vegetables like asparagus, carrots, or zucchini add color and nutrition.
Garlic bread on the side is perfect for soaking up every drop of that cowboy butter sauce. Adding baby spinach, cherry tomatoes, or sautéed bell peppers before serving increases the vegetable content.
For heartier appetites, serve over mashed potatoes or creamy polenta. Pair with sparkling water or iced tea for refreshing contrast. Consider serving alongside Garlic Butter Steak Bites for steak lovers, or pair with Buttery Steak Tortellini when entertaining. Creamy Garlic Parmesan Tortellini with Sausage and Broccoli offers similar pasta comfort, while Cajun Steak Tips in Cheesy Rigatoni Parmesan Sauce provides another spicy option.
