This recipe combines the rich, indulgent cream sauce you’d find in a steakhouse (often served over steaks or pasta) with the freshness of zucchini. It’s a perfect “date night at home” dish—elegant but surprisingly simple to make.
The key to the steakhouse flavor is a Parmesan-heavy cream sauce with a hint of garlic and shallot, finished with a touch of pasta water to make it velvety.
Steakhouse Style Creamy Spaghetti with Zucchini
Serves: 4
Prep time: 10 minutes
Cook time: 20 minutes
Ingredients
For the Pasta & Zucchini:
-
12 oz (350g) spaghetti (or bucatini/linguine)
-
2 medium zucchini, sliced into half-moons or matchsticks
-
1 tbsp olive oil
-
Salt and black pepper, to taste
-
Optional: Grilled steak (sirloin or ribeye), sliced, for serving
For the Creamy Steakhouse Sauce:
-
2 tbsp unsalted butter
-
1 large shallot, finely minced (or ½ small onion)
-
2 cloves garlic, minced
-
1 cup heavy cream
-
½ cup chicken or vegetable broth
-
1 cup freshly grated Parmesan cheese (plus more for garnish)
-
¼ tsp nutmeg (optional, but classic with creamy pasta)
-
Pinch of red pepper flakes (optional)
-
¼ cup pasta water (reserved)
Instructions
-
Cook the Pasta: Bring a large pot of salted water to a boil. Cook the spaghetti according to package directions until al dente. Before draining, reserve 1 cup of the starchy pasta water. Drain the pasta (do not rinse).
-
Cook the Zucchini: While the pasta cooks, heat 1 tbsp of olive oil in a large skillet over medium-high heat. Add the zucchini, season with a pinch of salt and pepper, and sauté for 3–4 minutes until just tender and lightly golden. Remove the zucchini from the skillet and set aside.
-
Build the Sauce: In the same skillet, reduce the heat to medium. Add the butter. Once melted, add the minced shallot and cook for 2 minutes until softened. Add the garlic and cook for 30 seconds until fragrant.
-
Make it Creamy: Pour in the heavy cream and chicken broth. Bring to a gentle simmer, then reduce the heat to low. Stir in the nutmeg, red pepper flakes (if using), and a pinch of black pepper.
-
Add the Cheese: Slowly whisk in the grated Parmesan cheese. Stir continuously until the cheese is melted and the sauce is smooth. Taste and adjust salt (remember the cheese is salty).
-
Combine: Add the cooked spaghetti and the sautéed zucchini to the skillet with the sauce. Toss everything together using tongs. If the sauce is too thick, add splashes of the reserved pasta water (start with ¼ cup) until it becomes silky and coats the pasta evenly.
-
Serve: Plate immediately. Top with extra grated Parmesan and a crack of fresh black pepper. For the full “steakhouse” experience, serve alongside or topped with sliced grilled steak.
How to Make it “Steakhouse Style”
To truly elevate this dish to steakhouse quality, consider these tips:
-
The “Steakhouse” Butter Finish: Just before serving, swirl in 1 tablespoon of cold butter off the heat. This emulsifies the sauce, giving it an incredible shine and rich flavor (called mantecatura in Italian cooking).
-
Freshly Grated Nutmeg: A tiny pinch of fresh nutmeg is the secret flavor in many steakhouse creamed spinach and Alfredo sauces. It adds warmth without tasting like “holiday spice.”
-
The Steak: Since it’s “Steakhouse Style,” the dish begs for protein.
-
Option A: Slice leftover grilled steak and lay it on top of the pasta.
-
Option B: While the pasta cooks, quickly sear a steak in a hot pan, let it rest, slice it, and serve it alongside the creamy spaghetti.
-
Substitutions & Variations
-
Lighter Version: Swap the heavy cream for half-and-half, but watch the heat (don’t let it boil) to prevent curdling. You may need a touch of cornstarch slurry to thicken it.
-
Add Protein (without steak): Cooked chicken, shrimp, or crispy pancetta would work beautifully.
-
Veggies: Add a handful of fresh spinach at the end with the zucchini and let it wilt into the sauce. Mushrooms are also a classic pairing.
