Low-Carb Garden Vegetable Egg Bake with Colby-Jack
This low-carb garden vegetable egg bake is thick, fluffy, and studded with tender peppers under a golden crust of Colby-Jack. You just sauté the greens, whisk the base, and let the oven do the heavy lifting while you pour coffee.
The Step Most Recipes Skip
The vegetables need a head start in the skillet before they see the oven. If you throw raw zucchini straight into the baking dish, it releases water and ruins the texture. Sauté the peppers and zucchini until they just start to soften. Then, take them off the heat.
The first time I tried a bake like this, I dumped the steaming vegetables right into the raw eggs. The eggs started cooking immediately into weird, rubbery streaks. Let the vegetables cool for five minutes. If you are impatient, spread them out on a plate to vent the steam faster.
Building the Base
While the vegetables cool down, build the liquid base. Crack the eggs and pour in the half-and-half. When you whisk the garlic powder into the dairy, it immediately smells exactly like a classic diner omelet.
Fold the spinach and two-thirds of the cheese into the bowl. Gently stir in the cooled vegetables. Pour everything into your greased dish. Bake for 30 minutes until the edges pull away slightly. Pull it out, add the rest of the cheese, and give it five more minutes to bubble.
What to Serve Alongside
This stands beautifully on its own, but it also anchors a larger spread. If you are having people over, serve it next to a sharp cucumber and tomato salad for some crunch. For a faster weekday morning, I usually grab a slice alongside a cold citrus smoothie to balance out the savory flavors.

Ingredients
Fresh Produce
- 1/2 cup Green bell pepper (chopped)
- 1/2 cup Red bell pepper (chopped)
- 3 cups Fresh spinach (roughly chopped)
- 1/4 cup Yellow onion (chopped)
- 1 medium Zucchini (chopped)
Dairy & Eggs
- 1 cup Shredded Colby-Jack or sharp cheddar cheese (divided)
- 8 large Eggs
- 1/2 cup Half-and-half (or whole milk for a lighter option)
Pantry & Seasonings
- 1/4 tsp Black pepper
- 1/2 tsp Garlic powder
- 1 tbsp Olive oil (extra virgin)
- 1/2 tsp Salt
Instructions
- Prepare the oven and pan: Preheat your oven to 350℉ (175℃). Lightly grease an 8×8-inch baking dish with non-stick spray or a little oil.
- Sauté the vegetables: Heat the olive oil in a large skillet over medium heat. Add the chopped onion, red and green bell peppers, and zucchini. Sauté for 5–7 minutes until the vegetables are tender-crisp. Remove the skillet from the heat and let the vegetables cool slightly for about 5 minutes (this prevents them from scrambling the raw eggs).
- Whisk the base: While the vegetables cool, crack the eggs into a large mixing bowl. Pour in the half-and-half, garlic powder, salt, and black pepper. Whisk thoroughly until the mixture is uniform and airy.
- Combine ingredients: Stir 2/3 cup of the shredded cheese and the chopped fresh spinach into the egg mixture. Add the slightly cooled sautéed vegetables and mix gently until well combined.
- Bake: Pour the mixture into the prepared baking dish. Place in the preheated oven and bake for 30 minutes. The edges should be golden, and the center should be mostly set.
- Melt the topping: Carefully remove the dish from the oven and sprinkle the remaining 1/3 cup of cheese over the top. Return to the oven for another 5 minutes, or until the cheese is melted and bubbly.
- Cool and serve: Remove from the oven and set on a wire rack. Let the casserole rest for at least 5 minutes to firm up before slicing into 9 even squares.
Notes
- Allergy Alert: This recipe contains eggs and milk (dairy). Use a dairy-free cheese alternative and unsweetened almond milk if needed, though this may alter the texture.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave.
