Tasty Keto Pasta Salad Without Pasta

Here is my favorite keto pasta salad without pasta recipe, with hearty turkey sausage, crispy zucchini chunks, black olives, roasted red peppers, and a tangy vinaigrette topped with fresh parmesan.

This pasta salad is perfect for summer cookouts or meal prep when you’re watching your carbs but don’t want to miss out on all the flavors of a classic pasta salad. My family can’t even tell there’s no actual pasta in it, and it’s become our go-to side dish for barbecues.

What Kind of Zucchini Should I Use?

For this keto pasta salad, you’ll want to pick smaller zucchini that are around 8 inches long, as the recipe suggests. Smaller zucchini tend to be firmer and less watery than their larger counterparts, which means they’ll hold up better as your “pasta” and won’t make your salad soggy. Look for zucchini that feel heavy for their size and have smooth, unblemished skin. If you can only find larger zucchini at the store, that’s okay too – just be aware that you might need to scoop out some of the seedy center before spiralizing or cutting them into noodle shapes.

Options for Substitutions

This keto-friendly salad is pretty forgiving when it comes to swaps:

• Italian sausage: You can use either turkey or pork sausage – both work great. If you want to switch things up, try chicken sausage or even crumbled cooked bacon for a different flavor profile.
• Zucchini: This is the pasta replacement, so don’t skip it! But if you’re not a zucchini fan, try yellow squash instead. You could also use spiralized cucumber for a crunchier texture, though you’ll want to pat it dry before mixing.
• Newman’s Own Olive Oil and Vinegar Dressing: Any good quality Italian vinaigrette will do the trick. You can also make your own by whisking together 1/3 cup olive oil, 3 tablespoons red wine vinegar, 1 teaspoon Dijon mustard, and some Italian herbs.
• Black olives: Kalamata olives or green olives work just as well if that’s what you have on hand. Each brings a slightly different flavor, so pick what you like.
• Roasted red peppers: Fresh bell peppers (any color) can replace jarred roasted peppers. Just dice them up raw, or roast them yourself for that smoky flavor.
• Parmesan cheese: Pecorino Romano or Asiago cheese make good substitutes if you’re looking for something different, though Parmesan really is ideal here for that classic Italian taste.

Watch Out for These Mistakes While Cooking

The biggest mistake you can make with this keto pasta salad is overcooking the zucchini, which turns it mushy and watery instead of maintaining that nice al dente texture you want – aim for just 4-5 minutes in the pan so it still has a slight bite.

Another common error is not draining the zucchini properly after cooking, as any excess moisture will dilute your dressing and make the salad watery, so let those slices sit in a colander for a few minutes or pat them dry with paper towels.

Don’t add the Parmesan cheese while everything is still hot, or it will melt into a clumpy mess rather than staying in nice shreds throughout the salad – wait until the mixture has cooled to room temperature.

Finally, make sure to drain your olives and roasted red peppers really well, as the liquid from these ingredients can also water down your salad and leave you with a pool of liquid at the bottom of the bowl.

What to Serve With Keto Pasta Salad?

This keto pasta salad is pretty filling on its own since it’s loaded with sausage and veggies, but it pairs really well with grilled chicken or steak if you want to make it a bigger meal. I love serving it alongside other low-carb dishes at summer cookouts, like burgers wrapped in lettuce or grilled shrimp skewers. It also works great as a side dish next to simple grilled fish or pork chops, and a fresh cucumber and tomato salad makes a nice light addition if you want something extra on the plate.

Storage Instructions

Store: This pasta salad keeps really well in the fridge for up to 4 days in an airtight container. Just give it a good stir before serving since the dressing might settle at the bottom. You might want to add a little extra dressing when you reheat it since the zucchini can absorb some of the liquid over time.

Make Ahead: You can totally prep this a day or two in advance, which actually makes the flavors even better as everything marinates together. I like to cook the sausage and spiralize the zucchini ahead of time, then toss everything together a few hours before serving so the zucchini doesn’t get too watery.

Serve: This salad is great served cold straight from the fridge, or you can let it sit at room temperature for about 20 minutes before eating. If the zucchini releases extra moisture after sitting, just drain off any excess liquid and toss with a bit more dressing and Parmesan.

• Calories: 1850-2100
• Protein: 85-100 g
• Fat: 145-160 g
• Carbohydrates: 55-70 g

Ingredients

For the cooked base:

• 3 tablespoons extra virgin olive oil
• 20 oz turkey sausage (sliced into 3/4-inch rounds)
• 3 medium zucchini (cut into 3/4-inch chunks for better surface browning)

For the assembly:

• 6 oz black olives, drained
• 12 oz roasted red peppers, cut into strips
• 1/2 cup vinaigrette dressing
• 1 cup fresh shaved parmesan cheese
• 1/2 teaspoon crushed red pepper flakes
• 2 tablespoons chopped fresh parsley
• Sea salt to taste
• Freshly ground black pepper to taste

Step 1: Prepare Mise en Place and Cook the Protein

• 3 tablespoons extra virgin olive oil
• 20 oz turkey sausage, sliced into 3/4-inch rounds
• 6 oz black olives, drained

Slice the turkey sausage into 3/4-inch rounds and cut the zucchini into 3/4-inch chunks—this size is crucial for even browning and optimal texture.

Drain the black olives and set aside.

Heat 3 tablespoons of olive oil in a large skillet over medium-high heat until shimmering.

Add the sausage slices in a single layer and let them brown undisturbed for 2-3 minutes per side until golden and caramelized.

Remove the sausage to a plate and set aside.

Step 2: Caramelize the Zucchini

• 3 medium zucchini, cut into 3/4-inch chunks

In the same skillet with the rendered sausage fat, add the zucchini chunks in a single layer.

Let them sit undisturbed for 3-4 minutes to develop a golden brown crust, then stir and cook for another 1-2 minutes until lightly caramelized on multiple sides.

The chunks should be tender but still have some texture—they shouldn’t be mushy.

Remove from heat and let cool for 2-3 minutes.

Step 3: Dress and Build the Salad Base

• warm zucchini from Step 2
• 1/2 cup vinaigrette dressing
• cooked sausage from Step 1
• 6 oz black olives, drained
• 12 oz roasted red peppers, cut into strips

While the zucchini is still warm, transfer it to a large mixing bowl and pour the 1/2 cup vinaigrette over it.

Stir gently and let sit for 5 minutes to allow the warm zucchini to absorb the dressing flavors.

This creates a more flavorful foundation than dressing everything at once.

Add the cooked sausage from Step 1, the drained olives, and the roasted red pepper strips, folding everything together gently.

Step 4: Season and Finish

• Sea salt to taste
• Freshly ground black pepper to taste
• 1/2 teaspoon crushed red pepper flakes
• 1 cup fresh shaved parmesan cheese
• 2 tablespoons chopped fresh parsley

Taste the salad and season generously with sea salt and freshly ground black pepper.

I like to add the red pepper flakes now rather than at the end—it allows them to bloom slightly in the warm salad and distribute their heat evenly throughout.

Fold in the fresh shaved parmesan cheese and the chopped fresh parsley gently to avoid breaking up the delicate cheese shards.

Serve at room temperature or chilled, depending on your preference.
