Summer Squash Pasta Skillet

There was this Tuesday last July when my CSA box overflowed with squash and I refused to let anything go to waste. I threw together whatever was in the fridge, not expecting much, but my roommate actually paused mid-bite and asked what I'd done differently. Now it's the dish that signals summer has properly arrived in our kitchen.

I made this for my parents' anniversary dinner when I was flat broke and trying to impress them with something elegant. My dad went back for thirds and quietly asked if I'd write down the recipe before they left, which is basically the highest compliment he knows how to give.

Ingredients

• 2 medium yellow summer squash, sliced into half-moons: These cook faster than zucchini and get sweeter in the pan
• 1 small zucchini, sliced into half-moons: Keep slices uniform so everything finishes cooking together
• 1 pint cherry tomatoes, halved: They burst and release juices that become part of the sauce
• 3 cloves garlic, minced: Dont let it brown or it turns bitter
• 1 small yellow onion, thinly sliced: Yellow onions are sweeter than white when they cook down
• 340 g (12 oz) short pasta: Penne catches the sauce best but anything with curves works
• 60 g (½ cup) freshly grated Parmesan cheese: Buy the wedge and grate it yourself for melting power
• 2 tbsp extra-virgin olive oil: This is the flavor base so use something you like
• ½ tsp crushed red pepper flakes: Even if you dont like heat, this tiny amount wakes everything up
• Salt and black pepper: Season at every layer for the best flavor
• ¼ cup fresh basil leaves, torn: Tear by hand instead of cutting to preserve the oils
• 2 tbsp chopped fresh parsley: Adds freshness and a little color pop at the end

Instructions

Cook the pasta:

Bring a large pot of salted water to boil and cook pasta until al dente, then reserve ½ cup of that starchy water before draining

Soften the onions:

Heat olive oil in your largest skillet over medium heat and cook sliced onions for 2 to 3 minutes until they start looking translucent

Add the garlic:

Stir in minced garlic and cook just 30 seconds until you can smell it—if it starts browning, move fast

Cook the squash:

Toss in summer squash and zucchini with salt, pepper, and red pepper flakes, cooking 4 to 5 minutes until tender but not mushy

Burst the tomatoes:

Add cherry tomatoes and stir for about 3 minutes until they soften and release their juices into the pan

Bring it together:

Dump in the drained pasta and toss everything, adding splashes of that reserved pasta water until you get a light glossy coating

Finish with herbs:

Pull the skillet off the heat and stir in Parmesan, basil, and parsley, then taste and adjust the seasoning

This became my go-to for potlucks because it travels well and serves a crowd without much effort. Last summer I made it for a block party and three different neighbors asked for the recipe, which is how I know it's a keeper.

Making It Your Own

Once you get the technique down, this recipe handles variations beautifully. Sometimes I toss in roasted red peppers from a jar or sun-dried tomatoes when I want deeper flavor.

Adding Protein

Cannellini beans make this heartier without changing the cooking time, though grilled chicken or shrimp work if you want meat. Just cook the protein separately and fold it in at the end.

Wine Pairings

A crisp Sauvignon Blanc cuts through the olive oil while a light Pinot Grigio complements the summer vegetables. Keep the wine simple and cold.

• Make a double batch because the leftovers are actually better the next day
• If you only have dried herbs, add them with the onions so they rehydrate properly
• Keep the red pepper flakes on the table for guests who want more heat

I hope this recipe finds you on some warm evening when cooking feels like a joy instead of a chore. Thats when it tastes the best anyway.

Recipe FAQs

→ Can I make this skillet ahead of time?

While best enjoyed fresh, you can prepare the vegetable mixture up to a day in advance. Reheat gently with a splash of water or olive oil before tossing with cooked pasta and fresh herbs.

→ What other vegetables work well in this dish?

Bell peppers, eggplant, or fresh spinach make excellent additions. You can also add roasted red peppers or sun-dried tomatoes for deeper flavor as suggested in the notes.

→ How do I prevent the pasta from becoming mushy?

Cook pasta until al dente, drain immediately, and reserve pasta water before adding to the skillet. The pasta finishes cooking in the sauce, so slightly undercooked is better than overdone.

→ Can I add protein to make it more filling?

Absolutely. Grilled chicken, shrimp, white beans, or chickpeas pair wonderfully. Add cooked proteins during the final toss so they heat through without overcooking.

→ What pasta shapes work best?

Short pasta with ridges or curves like penne, rotini, or fusilli catch the light sauce beautifully. The recommended shapes help hold onto the vegetables and herbs in every bite.
