Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 1 lb sirloin steak, cubed

• 9 oz cheese tortellini

• 1 cup heavy cream

• ½ cup grated Parmesan cheese

• 3 tablespoons unsalted butter

• 4 cloves garlic, minced

• 1 tablespoon Cajun seasoning

• 1 tablespoon olive oil

• ½ teaspoon salt

• ½ teaspoon ground black pepper

• 1 tablespoon chopped fresh parsley (optional)

Directions

1. Cut the steak into bite-sized cubes and season with Cajun seasoning, salt, and pepper. Mince the garlic.

2. Bring a large pot of salted water to a boil. Cook the tortellini according to package instructions, then drain and set aside.

3. In a hot cast iron skillet, heat olive oil over medium-high heat. Sear the steak cubes for 3–4 minutes, until well browned. Remove the steak from the skillet and set aside.

4. Reduce the heat to medium-low. In the same skillet, melt the butter and add the minced garlic. Sauté for 30–60 seconds until fragrant.

5. Return the steak to the skillet and toss in the garlic butter until evenly coated. Remove from heat.

6. In a separate saucepan, heat the heavy cream over medium-low heat. Stir in Parmesan cheese and continue stirring until melted and the sauce is smooth. Season with salt and pepper to taste.

7. Add the cooked tortellini to the Alfredo sauce and gently fold to coat evenly.

8. Plate the creamy tortellini and top with the garlic butter steak. Garnish with chopped parsley and additional Parmesan if desired.

Storage/Reheating

FAQs

What cut of steak works best?

Sirloin is ideal for this recipe due to its tenderness and flavor, but you can also use ribeye, strip steak, or filet.

Can I use store-bought Alfredo sauce?

Yes, but making your own with cream and Parmesan offers a fresher, creamier taste.

Is Cajun seasoning very spicy?

Cajun seasoning has a mild to moderate heat. You can adjust the amount to suit your spice preference.

Can I use frozen tortellini?

Fresh or refrigerated tortellini is preferred for texture, but frozen tortellini works as long as it’s cooked according to package instructions.

How do I know when the steak is done?

Steak cubes are usually done after 3–4 minutes of searing. They should be browned on the outside and slightly pink or fully cooked inside, depending on preference.

Can I prep this in advance?

You can cook the components ahead of time, but for best results, assemble and reheat gently right before serving.

How do I prevent the Alfredo sauce from separating?

Use low heat and stir continuously when making the sauce. Don’t let the cream boil.

What cheese alternatives work in Alfredo sauce?

Try asiago or Romano for a different flavor profile. A small amount of cream cheese can also enhance the creaminess.

Can I make this gluten-free?

Yes, use gluten-free tortellini and confirm your Cajun seasoning and Parmesan are gluten-free.

Does this dish freeze well?

It’s best enjoyed fresh, as the cream sauce and tortellini can change texture when frozen and reheated.
