These hearty, flavorful casseroles are easy to prepare the night before and can feed a crowd without requiring much morning effort. From savory scrambles to sweet bakes, these dishes are perfect for fueling the day while keeping everything plant-based and stress-free.

Let’s dive into how to plan, prep, and serve delicious vegan breakfast casseroles that everyone — even non-vegans — will love.

Why Make-Ahead Vegan Breakfast Casseroles Are Perfect for Thanksgiving Morning

Thanksgiving is all about togetherness, gratitude, and comfort — and breakfast should reflect that too. But when you’re hosting, simplicity is key.

Here’s why casseroles are the MVP of the vegan Thanksgiving morning menu:

  1. Minimal morning prep: Assemble the night before, refrigerate overnight, and just bake in the morning.

  2. Feeds a crowd: A single dish can easily serve 6–10 people.

  3. Budget-friendly: You can stretch ingredients like bread, tofu, and veggies for affordable yet hearty meals.

  4. Flexible: Great for using up leftover produce, stale bread, or even mashed potatoes.

  5. Comforting and festive: Warm, savory, and perfect for a chilly fall morning.

Whether you lean sweet (like a pumpkin French toast bake) or savory (like a tofu hash casserole), these vegan breakfast casseroles will make Thanksgiving morning feel effortless.

Essential Tips for Make-Ahead Success

Before we get to the recipes, here are a few tips to make sure your casseroles turn out perfectly every time.

  • Prep early: Most casseroles can be made 12–24 hours ahead. Cover tightly and refrigerate overnight.

  • Bake from cold: If taking directly from the fridge, add 5–10 minutes of baking time.

  • Use sturdy ingredients: Day-old bread, firm tofu, and hearty vegetables hold up best to overnight soaking.

  • Avoid sogginess: Don’t over-saturate bread or use watery vegetables without roasting or draining them first.

  • Make it your own: Mix and match flavors — think savory sausage-style seasoning or cozy apple-cinnamon sweetness.

Now, let’s explore the best vegan Thanksgiving breakfast casseroles that can be prepped ahead for a stress-free holiday morning.
