Easy Vegetable Bake has become my weekly meal prep staple because it’s like a healthier, veggie-packed version of pizza that lasts all week. This colorful casserole combines tender broccoli and cauliflower with a savory custard-like base and melted cheese on top. I love that it works perfectly for breakfast, lunch, or dinner and can be customized with whatever vegetables I have on hand.
The first Sunday I made this easy vegetable bake, I was looking for something that would give me healthy, grab-and-go meals for the entire week. As it baked, my kitchen filled with the aroma of garlic, paprika, and fresh parsley mixed with roasting vegetables. When I pulled it from the oven, golden and bubbling with melted mozzarella, I knew I had found a keeper. What makes this recipe so practical is how the vegetables stay tender but not mushy, and the egg-based custard holds everything together beautifully. I’ve made this vegetable casserole dozens of times now, and it never gets old because you can switch up the vegetables based on what’s in season.

Gather Your Ingredients
I always use a mix of broccoli and cauliflower as the base for this easy vegetable bake because they provide the perfect meaty texture. Pro tip: you can substitute any flour type like almond flour, oat flour, or gluten-free all-purpose flour to fit your dietary needs.
- 1 medium head broccoli, cut into medium florets
- 1 small head cauliflower, cut into florets
- 1 tablespoon olive oil (for sautéing)
- 1 small onion, diced
- 1/2 red bell pepper, sliced
- 3 eggs, lightly beaten
- 5 tablespoons olive oil
- 1 1/3 cups (315 ml) milk of choice
- 3/4 cup (94 g) flour of choice
- 1/2 cup grated Parmesan cheese
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- Salt and pepper to taste
- 1/3 cup (20 g) fresh parsley, chopped
- 1 cup (112 g) shredded mozzarella cheese
Any milk works perfectly in this recipe, whether you prefer dairy milk, almond milk, oat milk, or soy milk. The choice is yours!

Simple Steps to Make It
I recommend boiling the broccoli and cauliflower just until fork-tender to maintain some texture in your finished easy vegetable bake.
Step 1: Bring a large pot of water to a rolling boil. Add the cauliflower florets and bring back to a boil. Cook for 7 minutes, then add the broccoli florets. Continue cooking for another 2 minutes until the broccoli is just fork-tender but still has a slight bite. Drain both vegetables thoroughly and let them dry. This is important because excess water will make your bake soggy.
Step 2: While the vegetables cook, heat 1 tablespoon of olive oil in a small pan over medium heat. Add the diced onion and sauté for 3 minutes until it becomes translucent and fragrant. Remove from heat.
Step 3: Preheat your oven to 350°F (175°C). Take a 9×13 inch baking dish and add the drained broccoli, cauliflower, sautéed onion, and sliced red bell pepper. Spread everything out evenly in a colorful pattern and season with salt and pepper to taste.
Step 4: In a large bowl, whisk together the beaten eggs and 5 tablespoons of olive oil until well combined. Pour in the milk and whisk again until smooth.
Step 5: Add the flour, grated Parmesan cheese, paprika, and garlic powder to the egg mixture. Whisk until you have a smooth batter with no lumps. Stir in the chopped fresh parsley last.
Step 6: Pour this mixture evenly over the vegetables in the baking dish, making sure it reaches all the corners. Gently shake the dish to help the batter settle around the vegetables.
Step 7: Sprinkle the shredded mozzarella cheese evenly over the top of your easy vegetable bake.
Step 8: Bake for 40 to 45 minutes until the top is golden brown and the center is set. You’ll know it’s done when the edges are crispy and a knife inserted in the center comes out mostly clean.
Step 9: Allow the bake to cool for 10 minutes before slicing. This resting time helps everything set properly so your slices hold together beautifully.
Pro tip: For extra protein, add cooked diced chicken breast to the vegetable mixture before baking.
Common mistake to avoid: Don’t skip draining the vegetables well or your bake will be watery instead of nicely set.
What to Serve with Vegetable Bake
This easy vegetable bake is satisfying on its own but pairs wonderfully with simple sides that add variety to your meal.
Fresh Garden Salad: Crisp greens with a light vinaigrette provide a refreshing contrast to the warm, cheesy bake and add extra vegetables.
Crusty Bread: A slice of toasted sourdough or whole grain bread is perfect for soaking up any extra custard and makes the meal more filling.
Roasted Sweet Potatoes: The natural sweetness complements the savory vegetables while adding fiber and vitamins.
Sliced Avocado: Creamy avocado adds healthy fats and a cool, rich element that balances the baked vegetables perfectly.

Storage and Reheating Tips
Store leftover easy vegetable bake in an airtight container in your refrigerator for up to 5 days. This is what makes it perfect for meal prep throughout the week.
To reheat, I recommend using a small countertop oven or regular oven at 350°F for 10 to 12 minutes until warmed through. You can also reheat slices in a dry skillet over medium heat for 3 to 4 minutes per side, which crisps up the bottom beautifully. Microwave reheating works in a pinch but won’t give you that nice texture.
Pro tip: This vegetable bake can be frozen in individual portions for up to 2 months. Wrap slices individually in plastic wrap, then place in a freezer bag. Thaw overnight in the refrigerator before reheating.
Easy Vegetable Bake FAQs
Can I use different vegetables?
Absolutely! Mushrooms, zucchini, or spinach work great, but make sure to use something meaty like broccoli or cauliflower as your base for structure.

Yes, if you use gluten-free all-purpose flour or almond flour instead of regular flour. The recipe works perfectly with any flour substitute.

Use non-dairy milk, skip the Parmesan or use nutritional yeast, and use dairy-free mozzarella shreds for a completely dairy-free easy vegetable bake.
