The Complete Garlic Butter Beef Spaghetti in Cheddar Cream Sauce Recipe

This recipe serves 4‑6 people. It can easily be doubled.

Ingredients – For the Pasta:

• 12 oz (340g) spaghetti or other long pasta
• 1 tablespoon salt (for pasta water)

Ingredients – For the Beef and Garlic Butter Sauce:

1 lb (450g) lean ground beef (85/15 or 90/10)

4 tablespoons (½ stick) unsalted butter

6 cloves garlic, minced (about 2 tablespoons)

1 small onion, finely diced (optional)

1 teaspoon salt

½ teaspoon black pepper

1 teaspoon paprika

½ teaspoon red pepper flakes (optional, for heat)

Ingredients – For the Cheddar Cream Sauce:

2 cups (480ml) whole milk (or half‑and‑half for extra richness)

1 cup (240ml) heavy cream

2 cups (8 oz / 225g) shredded sharp cheddar cheese

½ cup (2 oz / 55g) grated Parmesan cheese

1 tablespoon cornstarch mixed with 2 tablespoons cold water (optional, for thickening)

Fresh parsley for garnish

Equipment:

Large pot for pasta

Large skillet or Dutch oven (12‑inch)

Whisk

Wooden spoon or spatula

Colander

Step‑by‑Step Instructions

Step 1 – Cook the Pasta

Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package directions until al dente. Reserve about 1 cup of pasta water before draining. Drain the spaghetti and set aside.

Step 2 – Brown the Ground Beef

While the pasta cooks, heat a large skillet or Dutch oven over medium‑high heat. Add the ground beef and cook, breaking it into small crumbles, until browned and cooked through, about 5‑7 minutes. If you are using onion, add it during the last 2 minutes of cooking. Drain any excess grease. Remove the beef from the skillet and set aside.

Step 3 – Make the Garlic Butter Base

In the same skillet, melt the butter over medium heat. Add the minced garlic and cook for 30‑60 seconds until fragrant, but not browned. If using red pepper flakes, add them now.

Step 4 – Create the Creamy Cheddar Sauce

Reduce the heat to low. Pour in the whole milk and heavy cream, whisking constantly. Bring to a gentle simmer (do not boil). Gradually add the shredded cheddar cheese and Parmesan cheese, whisking until smooth and fully melted. If the sauce is too thin, whisk in the cornstarch slurry and cook for 1‑2 minutes until thickened. Season with salt, pepper, and paprika.

Pro tip: Shred your own cheese from a block – pre‑shredded cheese contains anti‑caking agents that can make the sauce grainy.

Step 5 – Combine Beef and Sauce

Return the browned ground beef to the skillet with the cheese sauce. Stir to combine.

Step 6 – Add the Spaghetti

Add the cooked spaghetti to the skillet. Toss to coat every strand in the creamy cheddar sauce. If the sauce is too thick, add a splash of reserved pasta water to loosen it.

Step 7 – Serve

Garnish with fresh parsley and extra Parmesan cheese. Serve immediately.

Pro Tips for the Best Garlic Butter Beef Spaghetti

Follow these expert tips for perfect creamy cheddar pasta every time:

Shred your own cheese – Pre‑shredded cheese contains starches that prevent smooth melting. Shred from a block for a silky, lump‑free sauce.

Do not boil the cream sauce – High heat can cause the dairy to separate. Keep it at a gentle simmer.

Use whole milk and heavy cream – Lower‑fat milk will result in a thinner, less rich sauce.

Reserve pasta water – The starchy water helps loosen the sauce and helps it cling to the pasta.

Cook pasta al dente – It will continue to absorb sauce; slightly undercook it for the best texture.

Adjust the cheese blend – Sharp cheddar gives the best flavor, but you can use a blend of cheddar, Monterey Jack, or Gouda.

Make it spicy – Add extra red pepper flakes or a dash of cayenne.

Delicious Variations (Same Creamy Base)

Once you master the classic garlic butter beef spaghetti, try these fun twists. These creamy pasta variations will keep your dinners exciting.

1. Mushroom and Beef Cheddar Pasta

Sauté 8 oz of sliced cremini mushrooms with the beef. The earthy mushrooms add depth and umami.

2. Spinach and Artichoke Beef Pasta

Add 2 cups of fresh spinach (wilts into the sauce) and ½ cup of chopped artichoke hearts (drained). The spinach and artichoke add a delicious tang.

3. Spicy Jalapeño Cheddar Beef Pasta

Add 2 diced jalapeños (seeds removed for less heat) and an extra ½ teaspoon of cayenne. Use pepper jack cheese in addition to cheddar.

Add ½ cup of cooked crumbled bacon along with the beef. The smoky, salty bacon is a perfect match for the creamy cheddar sauce.

5. Broccoli Cheddar Beef Pasta

Steam 2 cups of broccoli florets and add them to the pasta. The broccoli adds color and nutrients. This is a broccoli cheddar beef pasta that is a complete meal.

Replace the spaghetti with 4 cups of zucchini noodles (zoodles) or hearts of palm pasta. Add the zoodles at the end, just to heat through (2‑3 minutes). This keto beef cheddar pasta is low in carbs.

7. Gluten‑Free Beef Cheddar Spaghetti

Use gluten‑free spaghetti. Ensure your other ingredients are gluten‑free. The sauce is naturally gluten‑free.

Replace half of the cheddar with smoked Gouda. The smoky, nutty flavor is incredible.
