Let’s Get Started
Step 1: Prepare the Zucchini
- Wash and thinly slice the zucchini into uniform rounds (about 1/8-inch thick).
- Pat dry with a paper towel to remove excess moisture—this prevents the dish from becoming watery.
Step 2: Make the Sauce
- In a medium saucepan, melt butter over medium heat.
- Add chopped onions and garlic, cooking until fragrant and soft.
- Stir in flour to make a roux, cooking for 1–2 minutes.
- Slowly whisk in milk or cream until smooth and thickened.
- Stir in shredded cheese until melted, creating a creamy sauce. Season with salt, pepper, and herbs.
Step 3: Layer the Dish
- Preheat oven to 375°F (190°C).
- In a greased baking dish, arrange a layer of zucchini slices.
- Pour some cheese sauce over the zucchini.
- Repeat layers until all zucchini and sauce are used.
- Top with Parmesan cheese and breadcrumbs for a golden crust.
Step 4: Bake
- Cover with foil and bake for 25 minutes.
- Remove foil and bake another 15–20 minutes, until the top is golden and bubbling.
Step 5: Serve
- Let the dish rest for 5 minutes before serving so the layers set.
Servings and Pairing
This recipe makes about 4–6 servings. It’s versatile and pairs well with a wide range of main courses:
- Grilled or roasted chicken for a balanced dinner.
- Steak or pork chops for a hearty pairing.
- Fish or seafood for a lighter, Mediterranean-style meal.
- Vegetarian main dishes like stuffed peppers or lentil loaf.
You can also serve scalloped zucchini with a crisp green salad and warm bread to complete the meal.
Variations
One of the best things about scalloped zucchini is how easily you can customize it. Here are a few ideas:
- Add Protein – Mix in cooked chicken, ham, or bacon for a more filling dish.
- Extra Veggies – Layer in mushrooms, bell peppers, or spinach.
- Different Cheeses – Try Gruyère for a French twist, or pepper jack for a little heat.
- Low-Carb Option – Use heavy cream and extra cheese, skipping breadcrumbs for a keto-friendly version.
- Vegan Version – Swap butter with olive oil, milk with plant-based alternatives, and use vegan cheese.
Storage Tips
- Refrigerator: Store leftovers in an airtight container for up to 3–4 days.
- Freezer: Freeze before baking for up to 2 months. When ready, bake directly from frozen (add extra time).
- Reheating: Warm in the oven at 350°F until heated through. Avoid microwaving too long, as it can make zucchini mushy.
FAQs
Can I use yellow squash instead of zucchini?
Yes! Yellow squash works beautifully in this recipe, either on its own or mixed with zucchini for more color.
Why is my scalloped zucchini watery?
Zucchini holds a lot of water. To prevent this, pat slices dry before layering, and don’t skip the flour-based sauce—it helps thicken the dish.
Can I make this ahead of time?
Absolutely. Assemble the dish up to a day in advance, cover, and refrigerate. Bake just before serving.
What’s the best cheese to use?
Cheddar and mozzarella are classic, but Gruyère or Parmesan add depth and nuttiness. Use what you love!
Is scalloped zucchini gluten-free?
Yes, if you use gluten-free flour or cornstarch instead of regular flour, and gluten-free breadcrumbs for topping.
