- 1 cup shredded mozzarella or provolone cheese: Melts wonderfully to bring creamy, cheesy richness.
- ¼ cup grated Parmesan cheese: Sprinkled on top, it creates a golden, savory crust.
- Fresh sage or basil leaves: Infuse the dish with fresh herbal notes that brighten every bite.

How to Make Baked Herb and Cheese Squash Casserole Recipe
Step 1: Preheat Your Oven
Start by warming your oven to 375°F (190°C). Getting the oven ready early ensures your casserole cooks evenly and develops that perfect golden crust by the end.
Step 2: Create a Flavorful Base
Spread a thin layer of tomato sauce across the bottom of your baking dish. This not only prevents sticking but infuses the dish with moisture and a touch of tanginess as everything bakes together.
Step 3: Layer with Love
Arrange your thinly sliced squash upright in the dish, alternating them with slices of cheese. Don’t forget to tuck fresh sage or basil leaves between the layers—this little step brings an herbaceous burst that elevates the entire casserole.
Step 4: Add the Finishing Touches
Drizzle olive oil generously over the layered squash, then sprinkle minced garlic, salt, and pepper on top. These simple seasonings make a world of difference, turning simple vegetables into an aromatic, savory delight.
Step 5: Bake Covered
Cover your dish with foil and bake for 30 to 35 minutes. This slow, gentle heat allows the squash to soften perfectly while blending the flavors inside.
Step 6: Broil to Golden Perfection
Remove the foil, sprinkle Parmesan cheese evenly on top, and return the dish to the oven. Bake an additional 10 to 15 minutes until the cheese melts into a bubbly, golden crust that’s irresistible.
Step 7: Garnish and Serve Warm
Finish with extra fresh sage or basil leaves for a pop of color and fragrance. Serve this cozy casserole warm to enjoy the best texture and flavors.
How to Serve Baked Herb and Cheese Squash Casserole Recipe

Garnishes
Brighten your casserole even more by adding fresh herb sprigs like extra sage or basil right before serving. A sprinkle of freshly cracked black pepper or a dash of chili flakes can also add a delightful contrast.
Side Dishes
This casserole pairs beautifully with light salads, roasted chicken, or even a hearty grain like quinoa or wild rice. Its richness complements lean proteins and fresh veggies perfectly.
Creative Ways to Present
For gatherings, serve portions in individual ramekins for a charming presentation. Or try layering with thin slices of zucchini or eggplant for added variety and a colorful layered effect that looks as good as it tastes.
Make Ahead and Storage
Storing Leftovers
Place leftovers in an airtight container and refrigerate for up to 3 days. The casserole stays tender, and the flavors even deepen after resting overnight.
Freezing
If you want a ready-to-go meal, freeze the fully baked casserole in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat gently in a 350°F (175°C) oven for about 15-20 minutes or until warmed through. This helps maintain the casserole’s texture without drying it out. Avoid microwaving if possible to keep the cheese beautifully melty.
FAQs
Can I use other types of squash in this recipe?
Absolutely! Yellow squash works wonderfully, but zucchini or even a mix of tender summer squashes can be substituted for similar results.
Is it okay to use pre-shredded cheese?
Yes, you can use pre-shredded mozzarella or provolone, though freshly shredded cheese tends to melt better and create a creamier texture.
Can I make this recipe vegan?
Definitely. Swap out the cheeses for vegan alternatives and use olive oil generously. Nutritional yeast sprinkled on top can add that cheesy flavor without dairy.
What can I do if I don’t have fresh herbs?
Dried herbs can work in a pinch, but fresh sage or basil really makes the flavor pop. If using dried, reduce the quantity as they are more concentrated.
How do I know when the squash is perfectly tender?
After baking covered for 30-35 minutes, insert a fork or toothpick into the squash slices—it should slide in easily without resistance for perfect tenderness.
