Vegan Breakfast Casserole

There’s something magical about a warm, hearty breakfast that brings people together—even better when it’s 100% plant-based. I created this vegan breakfast casserole on a chilly weekend morning when my family was craving something cozy and filling but still healthy and dairy-free.

It’s the kind of dish that you pull from the oven and serve right at the table, still bubbling, the aroma waking everyone up before the coffee even brews. Whether you’re serving brunch for a crowd, meal-prepping for the week, or just craving something beyond toast and smoothies, this casserole is your answer.

And if you’re wondering, “Can a vegan breakfast be hearty, satisfying, and crave-worthy?”—read on. You won’t want to miss this one.

Why I Love This Recipe

This vegan breakfast casserole checks all the boxes: comforting, make-ahead friendly, easy to customize, and surprisingly filling without any eggs or cheese. That’s the true magic here.

So many people assume that breakfast casseroles need to rely on animal-based ingredients to taste good or have structure. But this dish is a game-changer. Thanks to a clever combination of tofu, plant milk, and chickpea flour, you get that classic casserole texture—soft yet firm, savory, and satisfying.

It’s packed with vegetables for a nourishing start to your day, and the subtle mix of spices gives it just the right warmth and depth of flavor. You don’t miss anything. No eggs. No dairy. Just real, wholesome ingredients baked into one comforting dish.

It also freezes beautifully, so it’s perfect for anyone wanting to meal prep or reduce waste. Bonus: it tastes just as good (if not better) the next day.

Ingredients for Vegan Breakfast Casserole

Let’s talk ingredients. This recipe doesn’t require anything fancy—just real, easy-to-find staples that come together to create a surprisingly flavorful casserole.

Here’s what you’ll need:

For the “egg” base
The trick is to mimic the texture and richness of eggs without actually using them.

• Firm tofu: Crumbled and blended to create the “egg” feel. It’s protein-packed and holds everything together.
• Unsweetened plant-based milk: Oat, soy, or almond milk work well. This adds moisture and creaminess.
• Chickpea flour: This gives that baked, slightly custardy texture you associate with a traditional casserole.
• Nutritional yeast: Brings a cheesy, umami flavor that’s essential.
• Turmeric: A pinch for color and earthy flavor—makes the tofu look just like eggs.
• Garlic powder + onion powder: For an extra layer of flavor.
• Black salt (kala namak): Optional, but gives an eggy aroma and taste that’s truly uncanny.

For the vegetable filling
This part is fully customizable, but here’s my favorite mix:

• Baby spinach or kale: For greens and extra nutrients.
• Red bell pepper: Adds sweetness and color.
• Onion: A sautéed base that builds flavor.
• Mushrooms: Earthy and meaty—great texture.
• Shredded potato or hash browns: Either fresh or frozen, this adds substance and that breakfast-y vibe.

Extras (optional but great)

• Vegan cheese shreds: For meltiness on top.
• Chopped green onions: For garnish.
• Smoked paprika: Adds depth and a bit of smokiness.

The beauty of this casserole is that once you understand the base, you can mix and match with your favorite veggies, herbs, or even vegan sausage for added flavor.

How Much Time Will You Need

Here’s the good news: this vegan breakfast casserole can be ready with minimal active effort.

• Prep time: 20–25 minutes (depending on your chopping speed)
• Bake time: 45–50 minutes
• Cool and set time: 10 minutes

Total time: Around 1 hour 15 minutes from start to table.

This makes it a great weekend breakfast option or something to prepare ahead for busy weekdays.

How to Make This Vegan Breakfast Casserole

Let’s break it down step-by-step so you can easily follow along, even if you’ve never made a vegan casserole before.

Step – 1: Prep your baking dish and oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with a bit of olive oil or vegan butter.

Step – 2: Cook your veggies

Heat a skillet over medium heat with a splash of oil. Add the chopped onion and cook for 3-4 minutes until soft. Toss in mushrooms and red bell pepper. Cook another 5 minutes until everything is tender and golden. Finally, add in the spinach or kale and sauté until just wilted. Set aside.

Step – 3: Make the tofu “egg” mixture

In a food processor or blender, combine the crumbled tofu, plant milk, chickpea flour, nutritional yeast, turmeric, garlic powder, onion powder, and black salt (if using). Blend until smooth and creamy. It should be pourable but thick—like pancake batter.

Step – 4: Assemble the casserole

In a large mixing bowl, combine your cooked vegetables, shredded potato (or hash browns), and any add-ins like vegan sausage or cheese. Pour in the tofu mixture and gently fold everything together until well mixed.

Pour the mixture into your greased baking dish and spread it out evenly.

Step – 5: Bake until golden

Bake for 45–50 minutes, or until the top is golden and the center feels set when you press lightly with a spoon. If desired, sprinkle with vegan cheese in the last 10 minutes of baking.

Step – 6: Let it rest

Once out of the oven, let it sit for 10 minutes before slicing. This helps everything set and makes cutting easier.

Step – 7: Serve and enjoy

Slice into squares and serve warm with your favorite sides. Garnish with green onions or fresh herbs if desired.

Substitutions

Even though this recipe is already plant-based and allergy-friendly, there’s plenty of flexibility to adapt it to your preferences.

Don’t have tofu?
Use store-bought vegan egg replacers or a mix of soaked cashews and plant milk blended with spices.

No chickpea flour?
Swap it with all-purpose flour or oat flour for a similar texture, though chickpea gives the best eggy feel.

Want to skip potatoes?
Use cooked quinoa, brown rice, or even diced sweet potatoes instead. They all add a slightly different texture but still work well.

Trying to reduce oil?
Sauté the veggies in water or vegetable broth instead of oil, and skip the vegan cheese.

No nutritional yeast on hand?
You can leave it out, though the flavor will be less cheesy. Add a little extra garlic or miso paste for umami instead.

The goal here is to make this recipe work for you—your pantry, your taste, your lifestyle.

Best Side Dishes for Vegan Breakfast Casserole

To round out your breakfast table, here are three wonderful side dish ideas that pair perfectly with this casserole:

Fresh Fruit Salad
A light, refreshing balance to the savory casserole. Use melons, berries, and citrus for a bright touch.

Avocado Toast
Simple, classic, and satisfying. A slice of whole-grain toast topped with mashed avocado and a sprinkle of chili flakes works wonders.

Herbed Roasted Tomatoes
Pop cherry tomatoes in the oven with olive oil, thyme, and a pinch of salt. Roast until blistered for a juicy, flavorful side.

Serving and Presentation Tips

A beautiful breakfast is a beautiful start to the day. And with a casserole like this, it’s easy to make your breakfast table feel cozy, intentional, and inviting—even if you’re just serving yourself.

Here’s how to present your vegan breakfast casserole like a pro:

• Let it rest before slicing. This helps the casserole hold its shape and creates those neat, satisfying squares.
• Garnish with color. A sprinkle of freshly chopped parsley, green onions, or microgreens adds a pop of brightness and freshness.
• Serve in a ceramic baking dish. Instead of transferring it to another plate, use a rustic or white casserole dish—it’s oven-to-table friendly and retains heat beautifully.
• Add contrasting sides. Fresh fruit or something crispy like toast or roasted potatoes will balance the soft texture of the casserole.
• Stack with style. Plate the casserole square on top of a bed of greens or with a fan of sliced avocado on the side for an elegant touch.

Make it feel like a brunch moment—even on a weekday.

Tips and Tricks to Make This Recipe Even Better

This recipe is simple—but a few insider tips can take it from good to absolutely unforgettable.

• Squeeze your veggies. If you’re using frozen spinach or watery mushrooms, make sure to squeeze out any excess moisture before adding to the casserole mix. This keeps the texture firm, not soggy.
• Use black salt (kala namak). Just a pinch transforms the tofu base and makes it smell and taste like real eggs. It’s a little-known vegan secret ingredient.
• Let it chill overnight. Make the mixture the night before, refrigerate it, and bake in the morning. The flavors meld and deepen, making the dish even tastier.
• Top with vegan cheese near the end of baking. It keeps it from drying out and creates that melted, golden crust.
• Double the batch and freeze half. This casserole freezes well. Slice it into individual servings and wrap them tightly—you’ll thank yourself later.

Common Mistakes to Avoid

Even simple recipes have pitfalls. Here’s what to watch for:

• Over-blending the tofu mixture. Blend until smooth, but don’t overdo it or it may become too runny and difficult to set when baked.
• Skipping the resting period after baking. The casserole needs 10–15 minutes to settle and firm up. Slicing too early will result in a sloppy mess.
• Using too many watery vegetables. Zucchini, tomatoes, and mushrooms are delicious, but release water. Either roast or sauté them first and drain well.
• Under-seasoning. Tofu and potatoes are like blank canvases—don’t be shy with your seasoning. Taste the “egg” mixture before combining.
• Using sweetened plant milk. Always check the label. A vanilla or sweetened almond milk can throw off the whole flavor profile.

How to Store It

This vegan breakfast casserole is made for make-ahead magic. Here’s how to store it properly:

In the refrigerator:
Once cooled completely, cover tightly or store in an airtight container. It will last for up to 5 days in the fridge. Reheat individual slices in the microwave or oven at 350°F until warm.

In the freezer:
Wrap individual slices in foil or place in freezer-safe containers. It’ll stay good for up to 2 months. To reheat, let it thaw in the fridge overnight and warm in the oven until heated through.

Meal prep tip: Store portions in glass containers with lids so you can reheat and serve straight from the container.

FAQ

Can I make this casserole the night before?
Yes! You can prep the entire dish, cover it, and refrigerate overnight. Just bake it in the morning. Add 5–10 extra minutes to the baking time since it will be chilled.

What can I use instead of tofu?
If you’re soy-free, you can try a chickpea flour and plant milk-only base, or a blended white bean mix (like cannellini beans). They won’t be as fluffy, but still delicious.

Can I use frozen vegetables?
Absolutely. Just make sure to thaw and drain them well before adding, especially if using spinach or hash browns.

How do I know when the casserole is done?
The top should be golden and slightly firm to the touch. If a knife inserted in the center comes out clean (or mostly clean), it’s ready.

Is this gluten-free?
Yes—if you make sure your ingredients (especially the chickpea flour and hash browns) are certified gluten-free. Always double-check labels.
