Ingredients You’ll Need

For the Steak Bites:

• 1.5 lbs sirloin or ribeye steak, cut into bite-sized cubes
• Salt and pepper, to taste
• 1 tsp garlic powder
• 2 tbsp olive oil
• 2 tbsp butter

For the Tortellini Alfredo Pesto Sauce:

• 18 oz cheese tortellini (refrigerated or fresh)
• 1 tbsp butter
• 3 cloves garlic, minced
• 1 cup heavy cream
• ¾ cup grated Parmesan cheese
• ½ cup shredded mozzarella cheese (optional)
• ¼ cup basil pesto (store-bought or homemade)
• Salt and black pepper, to taste
• Fresh parsley or basil, for garnish

Preparation

Step 1: Bring a large pot of salted water to a boil. Cook the tortellini according to package directions until tender. Drain and set aside.

Step 2: Season the steak cubes with salt, pepper, and garlic powder. Heat olive oil in a large skillet over medium-high heat. Add the steak bites in a single layer and sear for 2-3 minutes per side, until browned and cooked to your liking. Remove and set aside.

Step 3: In the same skillet, reduce heat to medium and melt 1 tablespoon of butter. Add minced garlic and sauté until fragrant, about 1 minute.

Step 4: Pour in the heavy cream and bring to a gentle simmer. Stir in Parmesan cheese and mozzarella, allowing it to melt completely. Add pesto, then season with salt and pepper to taste.

Step 5: Add the cooked tortellini to the sauce and gently stir to coat. Fold in the steak bites. Warm everything together for 1–2 minutes. Garnish with parsley or basil before serving.

Variation

This dish is already bursting with flavor, but it’s also super adaptable to suit various dietary needs or preferences. Here are some creative variations you can try:

• Gluten-Free Option: Swap the regular cheese tortellini for a gluten-free version, or use gluten-free penne or fusilli pasta instead. Be sure to check that your pesto and Alfredo ingredients are gluten-free too.
• Vegetarian Twist: Skip the steak and add sautéed mushrooms, sun-dried tomatoes, or roasted red peppers. The tortellini and pesto Alfredo sauce already provide plenty of richness, so you won’t miss the meat.
• Lighter Version: For a lighter meal, use half-and-half instead of heavy cream and cut back on the cheese. You can also use grilled chicken or shrimp in place of steak for a leaner protein.
• Homemade Pesto: If you have fresh basil on hand, whip up a quick homemade pesto with basil, olive oil, garlic, pine nuts, and Parmesan. It adds a fresh and vibrant touch that elevates the entire dish.

These simple tweaks let you enjoy the creamy comfort of this meal while tailoring it to your health goals, pantry ingredients, or flavor preferences. Don’t be afraid to experiment, you might just create your new favorite version.

How to Serve

This dish is rich and satisfying on its own, but if you want to create a complete meal, there are a few great ways to round it out. Here’s how to make it dinner-party or weeknight-dinner perfect:

• With a Fresh Side Salad: Serve it with a crisp Caesar salad or a simple green salad with lemon vinaigrette to balance the richness of the Alfredo sauce.
• Add Garlic Bread: A warm slice of garlic bread or a buttery breadstick pairs beautifully, helping you soak up all that creamy sauce left on the plate.
• Roasted Vegetables: Try roasted broccoli, asparagus, or Brussels sprouts as a colorful and nutritious side that brings texture and freshness to the meal.
• Beverage Pairing: For drinks, sparkling water with lemon or a cold glass of iced tea works well. You can also try a basil-infused lemonade to play off the pesto flavor.

When plating, garnish with fresh herbs and a sprinkle of extra Parmesan to elevate presentation. Whether you’re feeding guests or just enjoying a night in, this meal feels special and comforting, like something you’d order at your favorite Italian restaurant but made right at home.

Recipe Tips

• Use high-quality steak for the best flavor and tenderness. Ribeye offers the most marbling, while sirloin is leaner but still flavorful.
• Cut the steak uniformly so all the pieces cook evenly and sear at the same time.
• Don’t overcook the tortellini. Drain it right when it becomes tender to avoid a mushy texture once added to the sauce.
• Grate your own cheese for smoother melting. Pre-shredded cheese can contain anti-caking agents that prevent it from fully blending into the sauce.
• Double the pesto Alfredo sauce if you like your pasta extra creamy or plan on leftovers. It thickens slightly as it cools.
• Store leftovers in an airtight container for up to 3 days. Reheat gently on the stove with a splash of milk or cream to loosen the sauce.

A few thoughtful steps during prep and cooking go a long way toward making this dish even more enjoyable and easy to pull off every time.

Cooking Note

• Don’t overcrowd the skillet when cooking steak bites. Give each piece space so it sears instead of steaming.
• Let the steak rest after searing. This helps retain the juices and keeps the meat tender when mixed into the sauce.
• Add pesto at the end of cooking. Cooking it too long can dull its bright, herby flavor.
• Use fresh tortellini when possible for a quicker cooking time and better texture.
• A splash of pasta water can help loosen the sauce if it gets too thick while combining.

FAQs

1. Can I use a different type of pasta if I don’t have tortellini?
Absolutely. While cheese tortellini adds extra flavor and richness, you can easily substitute it with penne, rigatoni, or even fettuccine. Just keep in mind that you’ll lose the cheesy filling, so consider adding extra cheese to the sauce if desired.

2. How do I store and reheat leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. When reheating, do it gently on the stovetop over low heat. Add a splash of milk or cream to help revive the sauce’s creamy consistency. Avoid microwaving at high heat, as that can make the steak tough and the sauce separate.

3. Can I prepare this recipe ahead of time?
Yes! You can prep the steak bites in advance and store them in the fridge until ready to cook. The pesto Alfredo sauce can also be made ahead and stored separately. When it’s time to eat, reheat the sauce and steak, boil fresh tortellini, and combine everything for a quick and easy meal.
