Ingredients

• 2 cups broccoli florets, bite-sized
• 2 cups cauliflower florets, bite-sized
• 1 medium zucchini, sliced into half-moons
• 1 red bell pepper, diced
• 1/2 yellow onion, finely chopped
• 3 cloves garlic, minced
• 4 large eggs
• 1/2 cup heavy cream or full-fat Greek yogurt
• 1.5 cups shredded sharp cheddar cheese (divided)
• 1/2 cup grated Parmesan cheese
• 1 teaspoon dried oregano
• 1/2 teaspoon smoked paprika
• Salt and black pepper to taste
• 1 tablespoon olive oil

Directions

Step 1: Preparation

Preheat your oven to 375°F (190°C) and lightly grease a 9×13 inch baking dish with olive oil or non-stick spray. Steam the broccoli and cauliflower florets for about 3-4 minutes until they are slightly tender but still crisp. This prevents the casserole from becoming watery. Drain them thoroughly and pat dry with a paper towel. In a small skillet, sauté the chopped onion and minced garlic in olive oil over medium heat until they are fragrant and translucent.

Step 2: Mixing the Base

In a large mixing bowl, whisk together the eggs, heavy cream (or Greek yogurt), dried oregano, smoked paprika, salt, and pepper until the mixture is smooth and well-combined. Stir in 1 cup of the shredded cheddar cheese and all of the Parmesan. Add the steamed broccoli, cauliflower, raw zucchini slices, diced bell peppers, and the sautéed onion and garlic to the bowl. Toss everything gently so the vegetables are evenly coated with the egg and cheese mixture.

Step 3: Baking and Plating

Pour the vegetable mixture into your prepared baking dish, spreading it out into an even layer. Sprinkle the remaining 1/2 cup of cheddar cheese over the top. Place the dish in the center of the oven and bake for 30 to 35 minutes, or until the eggs are set and the top is golden brown and bubbling. Remove from the oven and let the casserole rest for 5 minutes before slicing. Serve warm as a main dish or a hearty side.

Expert Tips for Perfect Healthy Veggie Casserole Low Carb No Meat

To ensure your casserole is never soggy, make sure you dry your steamed vegetables very well. Vegetables like zucchini release a lot of moisture, so slicing them thinly and even salting them briefly before adding can help. If you want an extra golden crust, turn on the broiler for the last 2 minutes of cooking, but watch it closely to prevent burning. Always use fresh garlic rather than powdered for a more robust flavor profile. For the best melting consistency, grate your cheese fresh from a block instead of using pre-shredded bags, which often contain anti-clumping starches that affect the texture.

Delicious Variations

You can easily customize this dish to suit your palate. For a spicy kick, add diced jalapeños or a teaspoon of red pepper flakes to the egg mixture. If you want a Mediterranean twist, swap the cheddar for feta cheese and add some kalamata olives and sun-dried tomatoes. To add a bit of crunch without the carbs, top the casserole with crushed pork rinds or almond flour mixed with melted butter before baking. You can also incorporate different low-carb vegetables like mushrooms, spinach, or asparagus depending on what is in season.

Frequently Asked Questions

Can I use frozen vegetables for this casserole?

Yes, you can use frozen broccoli and cauliflower. However, you must thaw them completely and squeeze out all excess water before mixing them in. If you don’t, the casserole will turn out watery and the eggs won’t set properly.

How long does this casserole stay fresh in the fridge?

This dish stays fresh for up to 4 days when stored in an airtight container in the refrigerator. It is a great option for meal prep because the flavors meld together even better the next day.

Can I make this recipe vegan?

To make this vegan, you would need to replace the eggs with a commercial egg replacer or a silken tofu blend, and use vegan cheese and a plant-based cream alternative like coconut cream or cashew cream. The texture will vary slightly but the flavor remains excellent.

Is this casserole freezer-friendly?

While you can freeze it, the texture of the vegetables (especially the zucchini) may become a bit softer upon thawing. If you plan to freeze it, bake it first, let it cool completely, and wrap it tightly. Reheat it in the oven to help restore some of the texture.

What can I serve with this veggie casserole?

Since this is a low-carb main dish, it pairs perfectly with a crisp green salad or a bowl of tomato basil soup. If you aren’t strictly low-carb, it also goes well with a side of quinoa or crusty whole-grain bread.
