• Salt and pepper to taste

How to Make Zucchini Noodles

Wash the zucchini thoroughly and trim off both ends.

Using a spiralizer, create long noodle strands. If you don’t own a spiralizer, you can use a julienne peeler or vegetable peeler to make ribbon-like noodles.

Place the zucchini noodles on paper towels and lightly sprinkle them with salt. Let them sit for about 10 minutes to draw out excess moisture. Pat dry before cooking. This simple step helps prevent watery noodles.

Step-by-Step Instructions

Step 1: Prepare the Pesto

In a food processor combine:

• Basil
• Parmesan
• Pine nuts
• Garlic

Pulse several times until finely chopped.

With the processor running, slowly drizzle in the olive oil until the mixture becomes smooth and creamy.

Add lemon juice, salt, and black pepper.

Blend again until well combined.

Taste and adjust seasoning if necessary.

Step 2: Heat the Skillet

Heat one tablespoon of olive oil in a large skillet over medium heat.

Avoid using high heat because zucchini cooks very quickly.

Step 3: Cook the Zoodles

Add the zucchini noodles to the skillet.

Cook for only 2–3 minutes while tossing gently.

The noodles should remain slightly firm, similar to al dente pasta.

Overcooking causes zucchini to become soft and watery.

Step 4: Add the Pesto

Turn off the heat.

Add the prepared pesto directly into the warm skillet.

Toss gently until every zucchini noodle is evenly coated with the vibrant green sauce.

The residual heat warms the pesto without overcooking the fresh basil.

Step 5: Garnish and Serve

Top with:

• Extra Parmesan cheese
• Fresh basil
• Toasted pine nuts
• Cherry tomatoes
• Red pepper flakes

Serve immediately while warm.

Tips for Perfect Zucchini Noodles

Don’t Overcook

The number one mistake people make is cooking zucchini too long.

Two to three minutes is enough.

The noodles should still have a slight bite.

Salt Before Cooking

Salting removes excess moisture and keeps the finished dish from becoming watery.

Add Pesto Last

Fresh basil loses flavor when cooked too long.

Always stir pesto into the noodles after removing the skillet from the heat.

Use Fresh Parmesan

Freshly grated Parmesan melts beautifully and adds much better flavor than pre-shredded cheese.

Make Pesto Ahead

Homemade pesto keeps well in the refrigerator for several days, making dinner even faster.

Delicious Protein Additions

Turn this simple side dish into a filling keto meal by adding:

• Grilled chicken breast
• Garlic butter shrimp
• Pan-seared salmon
• Steak strips
• Rotisserie chicken
• Italian sausage
• Crispy bacon
• Grilled tofu for a vegetarian option

Each protein pairs wonderfully with the fresh basil pesto.

Recipe Variations

This variation offers bold Mediterranean flavors while remaining keto-friendly.

Spicy Version

Mix in:

• Red pepper flakes

Perfect for anyone who enjoys a little heat.

Blend one ripe avocado into the pesto for an extra creamy texture and healthy fats.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 2 days.

Because zucchini naturally releases moisture, this recipe is best enjoyed fresh.

If storing, keep the pesto separate from the zucchini noodles whenever possible.

Can You Freeze It?

Freezing is not recommended.

Fresh zucchini becomes very soft after thawing.

However, homemade pesto freezes beautifully for up to 3 months.

Freeze it in small containers or ice cube trays for convenient portions.
