Cheddar-Zucchini Puff: A Taste of Home

My grandmother, bless her heart, had a garden that could feed a small army. Every summer, it was a vibrant explosion of colors and flavors, but inevitably, zucchini would take over. We’d find it lurking in every dish, from breads to fritters. While some attempts were less than stellar, her Cheddar-Zucchini Puff always stood out. It was a comforting, cheesy, and unexpectedly delicious way to tame the zucchini beast, and the memory of its warm, savory aroma still brings me right back to her sunny kitchen.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 25 minutes
• Total Time: 45 minutes
• Servings: 6
• Yield: 1 pan
• Dietary Type: Vegetarian

Ingredients

• 1 lb zucchini (about 4 cups sliced) or 1 lb crookneck yellow squash, sliced 1/4 inch thick
• 1/2 cup sour cream
• 1 egg yolk, beaten
• 1 tablespoon all-purpose flour
• 1/4 teaspoon onion salt
• 1/8 teaspoon black pepper
• 3/4 cup shredded cheddar cheese
• 1 egg white
• 2 tablespoons seasoned dry bread crumbs
• 1 teaspoon butter, melted

Equipment Needed

• Medium saucepan
• 8 x 1 1/2 inch round baking dish (or 8-inch square baking dish)
• Mixing bowls
• Whisk
• Measuring cups and spoons

Instructions

1. Preheat your oven to 350°F (175°C). Lightly grease an 8 x 1 1/2 inch round (or 8-inch square) baking dish.

2. In a medium saucepan, combine the sliced zucchini (or yellow squash) with a small amount of boiling water. Cover the saucepan and cook for 3-5 minutes, or until the zucchini is tender. Be careful not to overcook it, you want it to retain some texture.

3. Drain the cooked zucchini thoroughly. Press it gently to remove any excess water. Spread the drained zucchini evenly in the prepared baking dish.

4. In a medium mixing bowl, combine the sour cream, beaten egg yolk, flour, onion salt, and pepper. Stir until well combined.

5. Add the shredded cheddar cheese to the sour cream mixture and stir until evenly distributed.

6. In a separate, clean mixing bowl, beat the egg white with a whisk until stiff peaks form. Stiff peaks mean the tips stand straight up when you lift the whisk. This step adds lightness and volume to the puff.

7. Gently fold the beaten egg white into the sour cream and cheese mixture. Be careful not to overmix, as this will deflate the egg white and result in a less fluffy puff. Use a light hand and cut down through the mixture, then fold it over itself until just combined.

8. Spoon the sour cream and egg white mixture evenly over the zucchini in the baking dish.

9. In a small bowl, combine the seasoned dry bread crumbs and melted butter. Mix well until the bread crumbs are evenly moistened.

10. Sprinkle the buttered bread crumbs evenly over the egg mixture in the baking dish. This will create a golden and slightly crunchy topping.

11. Bake in the preheated 350°F oven for 20-25 minutes, or until the puff is golden brown and set. The center should be firm to the touch, and the edges should be lightly browned.

12. Let the Cheddar-Zucchini Puff cool slightly before serving. This allows the puff to set further and makes it easier to cut and serve.

Expert Tips & Tricks

• Don’t skip draining the zucchini! This is crucial for preventing a watery puff. If you have time, you can even salt the zucchini after slicing and let it sit for 30 minutes to draw out more moisture before cooking. Rinse and pat dry before proceeding.
• For an extra cheesy flavor, use a sharp or extra-sharp cheddar cheese. You can also experiment with other types of cheese, such as Gruyere or Monterey Jack.
• To make this ahead of time, assemble the puff up to the baking step. Cover tightly and refrigerate for up to 24 hours. Add the breadcrumb topping just before baking. You may need to add a few minutes to the baking time if starting from cold.
• If the bread crumbs are browning too quickly, loosely cover the baking dish with aluminum foil during the last 10 minutes of baking.
• For a richer flavor, try browning the butter before mixing it with the bread crumbs.

Serving & Storage Suggestions

Serve the Cheddar-Zucchini Puff warm as a side dish, a light lunch, or even a vegetarian main course. It pairs well with roasted chicken, grilled fish, or a simple salad.

Leftovers can be stored in the refrigerator for up to 3 days. Reheat gently in the oven or microwave. The texture may change slightly upon reheating, but the flavor will still be delicious.

While freezing is not recommended due to the dairy content, you can freeze individual slices. Wrap them tightly in plastic wrap and then aluminum foil. Thaw overnight in the refrigerator and reheat as above. Expect a noticeable change in texture.

FAQs (Frequently Asked Questions)

Q: Can I use pre-shredded cheese for this recipe?
A: Yes, you can use pre-shredded cheese, but freshly shredded cheese will melt more smoothly and evenly.

Q: What if my egg white doesn’t form stiff peaks?
A: Make sure your bowl and whisk are completely clean and dry. Any trace of fat can prevent the egg white from whipping properly.

Q: Can I use different types of squash?
A: Yes, you can experiment with different types of squash, such as butternut squash or acorn squash. Adjust the cooking time as needed, depending on the density of the squash.

Q: My puff turned out watery. What did I do wrong?
A: The most common cause of a watery puff is not draining the zucchini (or squash) thoroughly enough. Be sure to press out as much excess water as possible after cooking.

Q: Can I add meat to this recipe?
A: Yes, you can add cooked and crumbled bacon or sausage to the zucchini mixture for a heartier dish.
