Ingredients

1 ½ lbs sirloin or ribeye steak, cut into bite-sized cubes

1 tsp Cajun seasoning (or to taste)

½ tsp smoked paprika

½ tsp garlic powder

Salt & black pepper, to taste

2 tbsp olive oil

6 tbsp unsalted butter

4 cloves garlic, minced

½ tsp red pepper flakes (optional, for heat)

1 tsp Dijon mustard

Juice of 1 lemon

2 tbsp fresh parsley, chopped

1 tbsp fresh chives, chopped

12 oz cheese tortellini (fresh or refrigerated)

½ cup grated Parmesan cheese

½ cup reserved pasta water

Instructions

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 ½ cup of pasta water, then drain and set aside.

Step 2: Pat the steak pieces dry with paper towels. Season with Cajun seasoning, smoked paprika, garlic powder, salt, and black pepper. Heat olive oil in a large skillet over medium-high heat. Sear the steak bites for 2–3 minutes per side until browned and cooked to your preferred doneness. Remove the steak and set aside.

Step 3: 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 4: Return the cooked tortellini and steak bites to the skillet. Toss to coat with the cowboy butter sauce. Add reserved pasta water as needed to create a smooth, silky sauce. Stir in Parmesan cheese until melted and creamy.

Step 5: Serve immediately, garnished with extra Parmesan, freshly chopped parsley, and a sprinkle of Cajun seasoning for color and spice.

Tips & Variations

For extra heat, increase the amount of red pepper flakes or add a dash of hot sauce to the sauce.

Substitute chicken or pork cubes for steak if preferred.

Use fresh herbs like basil or thyme instead of parsley and chives for a different flavor profile.

To make it vegetarian, omit the steak and add sautéed mushrooms or roasted vegetables instead.

FAQs

Can I use frozen tortellini for this recipe?

Yes, frozen tortellini works well. Just increase the cooking time slightly and make sure to reserve some cooking water before draining.

How do I know when the steak bites are done?

Sear steak cubes until browned on all sides, about 2–3 minutes per side depending on thickness. For medium-rare, aim for an internal temperature of 130–135°F (54–57°C). Use a meat thermometer for best results.
