Great dishes shine when every ingredient has a purpose, and Spaghetti Squash with Late Summer Primavera is no exception.

Spaghetti squash: The star of the show—this gourd turns into golden, tender strands that mimic pasta but keep things light and naturally gluten-free.

Olive oil: Used in two parts—one for roasting and another for sautéing—this ingredient creates richness and helps the vegetables caramelize.
Salt and pepper: Essential for bringing out the natural sweetness of the veggies and enhancing every layer of flavor.

Yellow onion: Minced and sautéed, it gives a mellow backbone and sweetness to the sauce.
Garlic: Nothing says Italian-inspired quite like fresh garlic, which brings just the right kick of savory aroma.

Crushed tomatoes: The saucy base that ties everything together—look for a good-quality canned tomato for the best flavor.
Red pepper flakes (optional): Just a pinch adds gentle heat and depth without overwhelming the sauce.
Oregano: Earthy and robust, it gives the sauce its signature herbal character.

Sea salt and fresh ground pepper: Seasonings to taste—don’t be shy, they wake up every bite.
Eggplant: Cut into cubes, it soaks up the sauce while bringing a creamy texture and satisfying chunkiness.
Zucchini: These tender green cubes hold their shape and add freshness with every forkful.

Red pepper: Sweet and vibrant, it adds a pop of color and crunch.
Basil leaves: The epitome of late summer—basil weaves its sweet, peppery aroma throughout the dish.
Grated Parmesan (optional): For those who aren’t vegan, this is your salty, nutty finale!

How to Make Spaghetti Squash with Late Summer Primavera

Step 1: Prep and Roast the Spaghetti Squash

The first step in any `primavera` adventure is roasting your spaghetti squash to perfection. Start by preheating your oven to 400 degrees and lining a baking sheet—parchment paper is your friend for easy cleanup. Carefully trim the ends of the squash, then halve it lengthwise. Scoop out those seeds and give each half a good rubdown with olive oil, plus a sprinkle of salt and pepper. Place them cut-side down and let the oven work its magic for about 40 to 50 minutes, until the flesh is golden and fork-tender—the strands should pull away easily, creating those iconic “noodles.”

Step 2: Start the Sauce—Sauté Aromatics

While the squash roasts, kick off your sauce! In a saucepan, heat a tablespoon of olive oil and gently cook your onions and garlic until they’re soft and fragrant—no browning allowed. This sets a sweet, savory base for everything that follows and is the hidden hero behind every great tomato sauce.

Step 3: Build the Tomato Sauce

Now, pour in your crushed tomatoes, a sprinkle of oregano, red pepper flakes if you want some subtle heat, and a bit of salt and pepper. Stir everything together and let it come up to a simmer. Let it bubble gently for 15 minutes, allowing all those beautiful flavors to meld.

Step 4: Sauté Summer Vegetables

Grab a large skillet and heat the remaining olive oil on high. Once hot, toss in your diced eggplant, zucchini, and red pepper—season them well with salt and pepper. Sauté until they’re golden and tender, with a little caramelization on the edges. This quick, high-heat cooking keeps the veggies vibrant and ensures they won’t go mushy in the sauce.

Step 5: Combine and Simmer the Sauce

Add your sautéed vegetables and ribbons of basil right into the tomato sauce. Bring everything to a gentle simmer and cook together for another 30 to 40 minutes, stirring occasionally. This step infuses your sauce with big, garden-fresh flavor and the kind of hearty texture that’s integral to Spaghetti Squash with Late Summer Primavera.

Step 6: Fluff, Toss, and Serve

When your squash is ready, let it cool a moment, then use a fork to fluff the flesh into spaghetti-like strands. Transfer to a big bowl and spoon over as much vibrant primavera sauce as you like. Give it a gentle toss to distribute everything, taste, and adjust the seasoning. Finish with grated Parmesan if you want, and it’s ready to serve!

Garnishes

The finishing touch can be as simple or decadent as you like! A flurry of extra basil, a crack of black pepper, or a sprinkle of nutty Parmesan on top adds a fresh pop of flavor and a visual flourish. If you’re feeling whimsical, try some toasted pine nuts or even thin lemon zest strips for brightness.

Side Dishes

This dish pairs beautifully with crusty garlic bread or a leafy green salad tossed in a lemony vinaigrette. Both are perfect for sopping up any extra sauce. If you’re in a celebratory mood, set the table with an antipasti platter—think olives, marinated artichokes, or grilled vegetables—to complement the main event.

Creative Ways to Present

Try serving Spaghetti Squash with Late Summer Primavera straight from its roasted shell for rustic charm and easy clean-up—it looks gorgeous and feels special. You could also twirl it high in a pasta bowl with a basil sprig or pile on mini plates for tapas-style presentation at summer gatherings.

Make Ahead and Storage

Storing Leftovers

Leftover Spaghetti Squash with Late Summer Primavera is your ticket to an easy lunch the next day! Let everything cool, then store the squash noodles and sauce separately in airtight containers in the fridge. This helps preserve the squash’s texture and keeps everything tasting fresh for up to four days.

Freezing

The good news: the sauce freezes wonderfully, making it great for batch cooking. Spoon cooled primavera sauce into freezer-friendly containers or bags and freeze for up to three months. While the squash itself is best fresh, you can freeze it too, just be aware it may release a bit more water upon thawing.

Reheating

Warm the squash and sauce separately to keep the texture lively. Gently reheat in a skillet with a splash of water or in the microwave at half-power. Once hot, toss together and serve—finish with a fresh dusting of basil or Parmesan. Quick, delicious, and just as comforting as when first made!
