My Personal Experience
I first made this recipe on a warm summer day when I had a few yellow squashes that needed using. I didn’t want to spiralize or grill them—so I thought, “Why not bake them with cheese?” One batch later, I was hooked. The edges crisped up beautifully, and the flavor reminded me of garlic bread (minus the guilt!). Now I make this at least once a week—especially when I want a quick, cozy side without too much effort.
Required Equipment
Baking Sheet
Essential for even roasting. It allows the squash slices to crisp up nicely without becoming soggy.
Parchment Paper
Helps prevent sticking and makes cleanup a breeze—especially important when baking cheese.
Sharp Knife
Needed for slicing the squash into even, thin rounds to ensure they cook uniformly.
Mixing Bowl
Used to toss the squash with olive oil, garlic, and seasonings. I always use a medium-sized one that gives me enough space to coat everything well.
Oven
A preheated oven is key to getting that golden, bubbly Parmesan topping!
Ingredients & Substitutions
- 2 medium yellow squash, thinly sliced – This is the star ingredient. Yellow squash has a mild, slightly sweet flavor and bakes beautifully.
- 1 tablespoon olive oil – Helps the Parmesan stick and gives a crispy finish.
- 2 cloves garlic, minced – Adds depth of flavor. You can substitute with 1/2 tsp garlic powder if needed.
- 1/2 teaspoon salt – Balances the flavors.
- 1/4 teaspoon black pepper – Adds a touch of heat.
- 1 teaspoon Italian seasoning – Optional, but it really enhances the flavor. Substitute with dried oregano or thyme.
- 1 cup grated Parmesan cheese – The real flavor booster! For a dairy-free version, you could try nutritional yeast, but the texture and taste will be different.
How to Make Keto Parmesan Yellow Squash
- Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
- Prepare the squash: Wash and thinly slice the yellow squash into 1/4-inch rounds. Keep them as uniform as possible for even baking.
- Season: In a bowl, toss the squash slices with olive oil, minced garlic, salt, pepper, and Italian seasoning until well coated.
- Arrange: Spread the slices in a single layer on the prepared baking sheet. Avoid overlapping so they crisp up nicely.
- Top with cheese: Sprinkle the Parmesan cheese generously over the squash slices.
- Bake: Place in the oven for 18–22 minutes, or until the cheese is golden brown and the squash is tender.
- Cool slightly and serve: Let them cool for a few minutes so the cheese sets, then gently remove with a spatula.
Tips for This Recipe
- Use freshly grated Parmesan for the best melt and flavor.
- Don’t overcrowd the pan—overlapping pieces will steam instead of crisp.
- If you like extra crispiness, turn on the broiler for the last 2 minutes (but watch closely!).
- For a spicy kick, add crushed red pepper flakes to the seasoning mix.
Optional Additions
- Crushed red pepper flakes – For a spicy twist.
- Fresh herbs like parsley or basil – Sprinkle on top before serving.
- Lemon zest – Adds a bright contrast to the cheesy flavor.
- Crumbled cooked bacon – Adds smoky crunch and extra fat.
Serving Ideas
- Serve as a keto-friendly side for grilled chicken or steak.
- Add it to a charcuterie board with olives and cheeses.
- Enjoy it as a savory snack with a side of keto ranch dressing.
- Pile it on top of a keto salad bowl for added texture and flavor.
Storage Recommendations
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Reheat: Use the oven or air fryer for best texture—microwaving can make them soggy.
- Freezing: Not recommended, as squash becomes watery after thawing.
Frequently Asked Questions
Can I use zucchini instead of yellow squash?

Is Parmesan cheese keto-friendly?
Absolutely. Parmesan is low in carbs and high in fat, making it ideal for keto.
How do I get them extra crispy?
Make sure to slice thinly, avoid overlapping, and use the broiler for the final minute or two.
