Recipe Overview

Ingredients for Keto Garlic Herb Beef Spaghetti

This recipe uses simple ingredients that come together to create an incredibly flavorful meal.

For the Garlic Herb Beef

• 1 pound ground beef (85% lean)

• 2 tablespoons olive oil

• 4 cloves garlic, minced

• 1 small shallot, finely chopped

• 1 teaspoon dried Italian seasoning

• 1 teaspoon dried oregano

• 1/2 teaspoon dried basil

• 1/2 teaspoon smoked paprika

• 1/2 teaspoon onion powder

• 1/2 teaspoon salt, or to taste

• 1/4 teaspoon black pepper

• 1/4 teaspoon crushed red pepper flakes (optional)

• 1 tablespoon fresh parsley, chopped

For the Asiago Parmesan Sauce

• 3/4 cup heavy whipping cream

• 1/2 cup freshly grated Asiago cheese

• 1/2 cup freshly grated Parmesan cheese

• 2 tablespoons unsalted butter

• 1/4 cup low-sodium beef broth

• 1 clove garlic, minced

• 1/4 teaspoon black pepper

• 1/4 teaspoon Italian seasoning

For the Keto Spaghetti

• 4 medium zucchini, spiralized into noodles

• 1 tablespoon olive oil

• Pinch of salt

• Pinch of black pepper

Optional Garnishes

• Freshly chopped parsley

• Extra grated Parmesan

• Shredded Asiago

• Crushed red pepper flakes

• Fresh basil leaves

Step-by-Step Instructions

Step 1: Prepare the Keto Spaghetti

Wash the zucchini thoroughly and trim both ends.

Using a spiralizer, turn the zucchini into long, spaghetti-like noodles. If you don’t have a spiralizer, a julienne peeler can create thin strips.

Place the zucchini noodles on paper towels and lightly sprinkle them with salt. Allow them to rest for approximately 10 minutes to release excess moisture.

Pat the noodles dry before cooking.

This step is important because zucchini contains a significant amount of water. Removing some of that moisture helps prevent the finished sauce from becoming watery.

Step 2: Brown the Ground Beef

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.

Add the ground beef and break it apart using a wooden spoon or spatula.

Cook for approximately 6–8 minutes, stirring occasionally, until the beef is browned and cooked through.

Drain excess grease if necessary.

Add the chopped shallot and cook for another 2 minutes until softened.

Stir in the minced garlic, Italian seasoning, oregano, basil, smoked paprika, onion powder, salt, black pepper, and optional red pepper flakes.

Continue cooking for approximately 1 minute until the garlic becomes fragrant.

Transfer the seasoned beef to a plate and set aside.

Step 3: Make the Creamy Asiago Parmesan Sauce

Reduce the skillet heat to medium-low.

Add the butter and allow it to melt.

Stir in the minced garlic and cook for approximately 30 seconds, being careful not to burn it.

Pour in the beef broth and gently stir, scraping up any browned bits from the bottom of the skillet.

Add the heavy whipping cream and allow the mixture to warm gently.

Gradually stir in the freshly grated Asiago and Parmesan cheeses.

Continue stirring until the cheeses melt and the sauce becomes smooth and creamy.

Season with black pepper and Italian seasoning.

Avoid boiling the sauce, as excessive heat can cause the cheese to separate or become grainy.

If the sauce becomes too thick, add a small splash of beef broth until it reaches your preferred consistency.

Step 4: Combine the Beef and Sauce

Return the cooked ground beef to the skillet containing the cheese sauce.

Stir thoroughly so every piece of beef becomes coated in the creamy Asiago Parmesan mixture.

Allow everything to simmer gently for 2–3 minutes.

Taste the sauce and adjust the seasoning if needed.

Because Asiago and Parmesan naturally contain salt, it’s best to taste before adding additional salt.

Step 5: Cook the Zucchini Spaghetti

Heat the remaining tablespoon of olive oil in a separate skillet over medium-high heat.

Add the spiralized zucchini noodles.

Sauté for approximately 2–3 minutes, tossing gently until the noodles are just tender.

Avoid overcooking them. Zucchini noodles should retain a slightly firm texture rather than becoming soft and mushy.

Remove the skillet from the heat and drain any excess liquid.

Step 6: Bring Everything Together

Add the cooked zucchini noodles to the skillet with the garlic herb beef and Asiago Parmesan sauce.

Using tongs, gently toss everything together until the noodles are evenly coated.

Warm the mixture for approximately 30–60 seconds, just long enough to combine the ingredients.

Remove from the heat.

Step 7: Garnish and Serve

Divide the spaghetti among four serving bowls.

Top each portion with freshly chopped parsley, additional Parmesan, and a sprinkle of Asiago cheese.

For a little heat, finish with crushed red pepper flakes.

Serve immediately while the sauce is warm and creamy.

Tips for Making the Best Keto Garlic Herb Beef Spaghetti

1. Use Freshly Grated Cheese

Freshly grated Asiago and Parmesan melt more smoothly than many packaged shredded cheeses.

Pre-shredded cheese often contains anti-caking ingredients that can affect the texture of creamy sauces.

2. Don’t Overcook the Zucchini Noodles

One of the biggest mistakes when preparing zucchini spaghetti is cooking the noodles too long.

They need only a few minutes in a hot skillet.

Overcooking releases additional moisture and can make the noodles soggy.

3. Choose Flavorful Ground Beef

Ground beef with some fat provides rich flavor and helps keep the dish satisfying.

An 85% lean blend offers a good balance between flavor and fat content.

You can also use leaner ground beef if preferred.

4. Keep the Cheese Sauce on Low Heat

High heat can cause cheese-based sauces to become oily or grainy.

Warm the cream gently and gradually incorporate the cheeses while stirring.

5. Add Fresh Herbs Before Serving

Fresh parsley or basil adds brightness and balances the richness of the beef and cheese.

Even a small amount makes a noticeable difference.

Delicious Keto-Friendly Variations

One of the best things about this recipe is how easily you can customize it.

Garlic Mushroom Beef Spaghetti

Add 1 cup of sliced mushrooms when cooking the shallot.

Mushrooms provide an earthy flavor that pairs beautifully with garlic and Parmesan.

Spicy Asiago Beef Spaghetti

Increase the crushed red pepper flakes to 1/2 teaspoon and add a pinch of cayenne pepper.

This creates a slightly spicy version that complements the creamy sauce.

Spinach and Garlic Beef Spaghetti

Add 2 cups of fresh baby spinach to the beef and sauce during the final minutes of cooking.

The spinach wilts quickly and adds extra vegetables without significantly increasing carbohydrates.

Keto Chicken Spaghetti

Replace the ground beef with cooked, shredded chicken.

The Asiago Parmesan sauce works equally well with chicken and provides a delicious alternative.

Extra-Cheesy Keto Spaghetti

Add another 1/4 cup of shredded Asiago for an even richer sauce.

Keep in mind that adding cheese will increase the calories and fat content.

What to Serve with Keto Garlic Herb Beef Spaghetti

Although this spaghetti is satisfying on its own, pairing it with a simple side dish can create a complete dinner.

Garlic roasted broccoli: Roasted broccoli seasoned with garlic, olive oil, and Parmesan complements the creamy pasta.

Caesar salad: A Caesar salad without croutons provides a crisp contrast to the rich beef and cheese sauce.

Roasted asparagus: Oven-roasted asparagus with olive oil and black pepper makes an easy keto-friendly side.

Sautéed mushrooms: Butter-sautéed mushrooms add another layer of savory flavor.

Keto garlic bread: Low-carb garlic bread made with almond flour can help turn this recipe into an Italian-inspired dinner.

Estimated Nutritional Information

Net carbohydrates are calculated by subtracting dietary fiber from total carbohydrates.

The low carbohydrate content makes this recipe a potential fit for many ketogenic meal plans, depending on individual daily carbohydrate targets.

How to Store and Reheat Leftovers

This recipe tastes best freshly prepared, but leftovers can be stored for another meal.

Refrigeration: Place leftovers in an airtight container and refrigerate for up to 3–4 days.

Reheating: Warm gently in a skillet over low heat. Add a splash of cream or broth if the sauce has thickened.

Freezing: The cooked beef and cheese sauce can be frozen separately for up to 2 months. However, zucchini noodles do not freeze particularly well because they release moisture after thawing.

For the best texture, prepare fresh zucchini noodles when reheating frozen sauce.

Refrigerate leftovers promptly and reheat thoroughly to 165°F.
