This gourmet-style garlic butter steak tortellini combines tender steak bites with cheesy pasta and a homemade Alfredo sauce for a restaurant-quality dinner right at home. It's become my go-to recipe when I want to impress guests without spending hours in the kitchen.
I first created this dish when my husband requested something special for our anniversary but I had limited time. The combination of juicy steak and creamy tortellini was such a hit that it's now our tradition for celebrating milestones.
Ingredients
- Steak bites: Using sirloin or ribeye for the perfect texture and flavor that stands up to the rich sauce
- Butter: Creates the foundation for both the steak sear and creamy sauce while adding richness
- Fresh garlic cloves: Provide aromatic flavor that canned versions simply cannot match
- Cheese tortellini: Offers pockets of extra cheesy goodness in every bite
- Heavy cream: Creates the silky base for a restaurant-quality Alfredo sauce
- Freshly grated Parmesan cheese: Melts beautifully and provides complex flavor notes that pre-shredded varieties lack
Step-by-Step Instructions
- Cook the Tortellini:
- Bring a large pot of generously salted water to a rolling boil before adding your tortellini. Cook according to package directions which typically takes 7-9 minutes for refrigerated varieties. The pasta should be tender but still have a slight bite to it. After draining, a light drizzle of olive oil prevents sticking while you prepare the other components.
- Sear the Steak Bites:
- Create a flavor base by melting butter in a hot skillet then adding minced garlic just until fragrant. This infuses the butter with garlic essence without burning the delicate aromatics. When adding steak bites, ensure they have space between each piece for proper browning. A good sear requires patience and a hot pan. The caramelization that happens during this process creates deep flavor compounds that elevate the entire dish.
- Craft the Alfredo Sauce:
- Using the same skillet capitalizes on the fond leftover from searing the steak. This browned residue contains concentrated flavors that will incorporate into your sauce. When adding the heavy cream, do so gradually while stirring to create a smooth emulsion. The Parmesan should be added in batches to ensure it melts evenly without clumping. Your sauce is ready when it coats the back of a spoon and leaves a clear path when you run your finger through it.
- Combine Components:
- Gently fold the tortellini into the Alfredo sauce ensuring each pasta piece gets evenly coated. Allow them to simmer together briefly which helps the sauce penetrate the pasta for maximum flavor. The brief marriage of components allows the starchy exterior of the pasta to further thicken the sauce naturally.
- Plate and Serve:
- Arrange the sauced tortellini as the base layer then strategically place the steak bites on top for visual appeal. The final drizzle of garlic butter adds a glossy finish and carries aromatic compounds that enhance the eating experience.

You Must Know
- This dish contains approximately 950 calories per serving making it a satisfying main course
- The steak provides excellent protein while the Parmesan delivers calcium
- Leftovers maintain quality for up to 3 days in the refrigerator
- The technique of using one pan for multiple components builds incredible depth of flavor
The heavy cream is truly the unsung hero of this recipe. While many home cooks try to substitute lighter options, I discovered through multiple tests that full-fat cream creates a sauce that remains stable and doesn't break when reheated. My family particularly loves gathering around this dish on cold winter evenings when comfort food becomes essential.
Perfect Pairing Suggestions
This rich pasta dish pairs beautifully with bright, acidic sides that cut through the creaminess. Consider serving it alongside a simple arugula salad with lemon vinaigrette or roasted asparagus with a squeeze of fresh lemon. The bright, sharp flavors balance the decadent main course perfectly. For special occasions, a glass of medium-bodied red wine like Merlot or Sangiovese complements both the beef and creamy elements.
Make-Ahead Options
You can prepare components of this dish separately up to a day in advance to streamline dinner preparation. Cook the tortellini until just slightly underdone, toss with a bit of olive oil, and refrigerate. The Alfredo sauce can be made ahead and gently reheated with a splash of cream to restore its silky texture. The steak should always be cooked just before serving for optimal tenderness and flavor, though you can have it cut and seasoned in advance.

Temperature Matters
The success of this dish relies heavily on temperature management throughout the cooking process. When searing steak, your pan must be hot enough to create a proper crust while keeping the interior juicy. The ideal internal temperature for medium-rare steak bites is 130-135°F. For the Alfredo sauce, keep the heat medium to medium-low to prevent the cream from breaking and the cheese from becoming grainy. Too high heat can cause the sauce to separate, while too low heat might not allow it to thicken properly.
Frequently Asked Questions
- → What type of steak works best for this dish?
Sirloin or ribeye steak is recommended for its tenderness and flavor. Ensure the steak is cut into bite-sized pieces for even cooking.
- → Can I use frozen tortellini?
Yes, but adjust the cooking time according to the package instructions. Fresh or refrigerated tortellini offers the best texture and flavor.
- → How can I achieve a perfect sear on the steak?
Make sure the steak is at room temperature before cooking. Heat the skillet until hot, avoid overcrowding the pan, and sear each side for a few minutes until a crust forms.
- → Can I make the Alfredo sauce ahead of time?
It’s best to prepare the sauce fresh, as it can thicken over time. However, you can reheat it gently over low heat while stirring to maintain its creamy texture.
- → What can I substitute for Parmesan cheese?
For a similar flavor profile, you can use Pecorino Romano or Grana Padano. If you’re looking for a less sharp taste, try a mild grated cheese like Asiago.
