At Sweet C’s, I add lots of tips in all of my recipes – because I am a home cook without any formal training, and I find I am more confident making dishes when I understand why it works, and what each ingredient means to the flavor of a recipe – my goal is for even the most beginner home cook to feel empowered in the kitchen.

I want each reader to walk away with a solid knowledge of each recipe, with all of the tips I’ve gathered from extensive testing of each recipe. I also answer questions my friends and family have asked about my recipes, to help everyone better understand the processes we use – and why!

Spaghetti Squash With Mozzarella, Tomatoes, and Basil

This dish is one of my favorite multitaskers. It is great for a healthy meal (spaghetti squash is incredibly low-calorie), and the addition of cheese and tomatoes makes it a delicious pasta-like dish that is perfect as an appetizer or a meat-free main dish!

This dish is great in fall with fresh squash, basil, and tomatoes from the garden – but you can make it anytime you can find good tomatoes and spaghetti squash.

It’s also great hot – and cold, served like a pasta salad – so it is perfect for meal prep or work lunches.

How to Make Caprese Baked Spaghetti Squash

To make this recipe, we will need the following ingredients:

  • Spaghetti Squash: Serves as the base, offering a light, mildly sweet, and slightly nutty flavor. It’s a great low-carb and gluten-free substitute for traditional pasta.
  • Olive Oil: Adds richness and helps in roasting the squash, bringing out its natural sweetness.
  • Campari Tomatoes: These tomatoes are sweeter and juicier, adding a burst of fresh flavor and a vibrant color.
  • Mozzarella Balls: Introduce a creamy, soft texture and a mild, milky taste. They add a delightful contrast to the other textures.
  • Basil: This herb is quintessential in Caprese, offering a fresh, peppery, and slightly sweet flavor.
  • Rosemary: Adds a fragrant, earthy, and slightly lemon-pine flavor, which complements the squash beautifully.
  • Pine Nuts: Provide a subtle nutty crunch, adding another layer of texture.
  • Red Pepper Flakes: A pinch can add a slight kick, balancing the dish’s sweetness with a bit of heat.
  • Italian Herbs Seasoning: Typically a blend of herbs like oregano, thyme, and basil. This adds a classic Italian flavor that ties all the ingredients together.

Once you’ve gathered your ingredients, we will use the following process:

  1. Preheat the Oven: Preheat your oven to 375ยฐF (190ยฐC).
  2. Prepare the Squash: Carefully cut the spaghetti squash in half lengthwise. Use a spoon to scoop out the seeds and any stringy bits from the center.
  3. Season and Bake: Place the two halves of the squash, cut-side up, on a baking sheet. Place 1 tablespoon of butter in each half. Season the squash with 1 teaspoon of garlic salt and 1/2 teaspoon of Italian herbs.
  4. Marinate the Cheese: In a small bowl, add olive oil, chopped basil, red pepper flakes, salt, diced tomatoes, chopped rosemary and mix. Let marinate as squash bakes.
  5. Bake the Squash: Place the baking sheet in the preheated oven and bake for about 30-40 minutes or until the squash is tender. The flesh should easily separate into spaghetti-like strands with a fork.
  6. Sautรฉ the Squash: After squash has baked and been shredded, toss in the skillet to coat with the butter and oil. Season with the remaining garlic salt and Italian herbs. Sautรฉ for about 5-7 minutes, or until the squash is heated through and has absorbed the flavors.
  7. Mix: Add caprese salad to baked spaghetti squash and toss. Mix well.
  8. Serve: Plate the sautรฉed spaghetti squash and top it with grated Parmesan cheese, red pepper flakes (adjust to your desired level of spiciness), and a pinch of minced parsley for a pop of freshness. I like to serve spaghetti squash back in the hollowed-out shell for a fun presentation.
  9. Enjoy: Your delicious and buttery spaghetti squash is ready to be enjoyed as a flavorful and low-carb side dish or even as a light main course.

Tips and Tricks for Perfect Caprese Baked Spaghetti Squash

Choose the Right Squash: Look for spaghetti squash that’s firm and free from soft spots or blemishes. Size-wise, a medium squash is usually the best for even cooking.

Roasting the Squash: Cut the squash in half lengthwise and remove the seeds. Brush with olive oil and season with salt and pepper. Roast cut-side down until tender. This method helps caramelize the edges, adding more flavor.

Fork Fluffing: Once baked, let the squash cool slightly, then use a fork to scrape out the flesh. This technique turns the squash into spaghetti-like strands.

Quality Ingredients for Caprese: Use ripe Campari tomatoes, fresh mozzarella, and fresh basil leaves for the best taste. The quality of these ingredients greatly influences the dish.

Seasoning the Squash: Before adding the Caprese mixture, season the squash strands with a bit more olive oil, salt, and pepper. This ensures every bite is flavorful.

Balancing the Flavors: Drizzle the finished dish with a good quality balsamic glaze or reduction. It adds a sweet and tangy contrast to the fresh flavors.

Garnish Wisely: A sprinkle of fresh basil on top not only adds freshness but also makes the dish visually appealing.

Cheese Considerations: Tear the mozzarella balls into smaller pieces for even distribution, and add them while the squash is still warm so they melt slightly.

Toasting Pine Nuts: If using pine nuts, toast them lightly in a dry pan to enhance their flavor and add a nutty crunch.

Serving Immediately: Serve the dish right after assembling to enjoy the contrast of warm squash and cool, fresh Caprese salad.

Customizing: Feel free to add extras like grilled chicken for protein or a sprinkle of red pepper flakes for a little heat.

Cooking in Stages: You can roast the squash ahead of time and then reheat it briefly in the oven before adding the Caprese toppings.

FAQs

What is Spaghetti Squash?

It’s a winter squash that, when cooked, separates into strands similar to spaghetti noodles. It’s low in calories and carbs but high in vitamins and minerals.

How Do I Cut Spaghetti Squash?

Cut it lengthwise from stem to base. Be sure to use a sharp knife and exercise caution, as the squash can be quite tough.

Can I Cook the Squash in the Microwave?

Yes, for a quicker method, you can microwave the squash. Just cut it in half, remove the seeds, and cook it cut-side down in a dish with a little water for about 10-15 minutes.

How do I know when spaghetti squash is done?

The flesh should be tender and easily shredded with a fork into strands.

Can I use different cheeses?

Absolutely! While fresh mozzarella is traditional for Caprese, feel free to experiment with other cheeses like burrata or feta.

What tomatoes are best for caprese?

Ripe, juicy tomatoes like Campari, Roma, or cherry tomatoes work well. The key is that they should be fresh and flavorful.

Can I make this more filling?

Add protein like grilled chicken or chickpeas, or bulk it up with leafy greens like spinach or arugula.

Can I prepare this dish in advance?

You can roast the squash ahead of time and store it in the refrigerator. When ready to eat, reheat the squash and add the fresh Caprese toppings.

How should I serve this dish?

Serve it warm with the Caprese mixture on top. You can drizzle with balsamic glaze and add fresh basil for garnish.

What to Serve With Caprese Baked Spaghetti Squash

Salad: A fresh garden salad with a variety of greens, cherry tomatoes, cucumbers, and a light vinaigrette dressing pairs well with the richness of the Caprese spaghetti squash.

Bread: A side of crusty Italian bread or garlic bread can be great for soaking up any extra sauce and adding a crunchy texture to your meal.

Wine: A glass of white wine, such as Pinot Grigio or Chardonnay, complements the flavors of the Caprese. If you prefer red, a light-bodied wine like Pinot Noir can also pair nicely.

Soup: A light soup, such as a tomato basil or a minestrone, can be a great starter that echoes the Italian flavors in the spaghetti squash.

Grilled Vegetables: Grilled asparagus, zucchini, or bell peppers add a nice charred flavor and provide a healthy and colorful side dish.

Baked Caprese stuffed squash with mozzarella.
Delicious garlic butter baked spaghetti squash tossed with caprese salad – diced tomatoes, chopped basil, herbs, and mozzarella balls.

  • 1 sprig rosemary, chopped

  • Carefully cut the spaghetti squash in half lengthwise. Use a spoon to scoop out the seeds and any stringy bits from the center.

Toss them in the skillet to coat them with the oil. Sautรฉ for about 5-7 minutes, or until the squash is heated through and has absorbed the flavors.
