Everything Bagel Vegetarian Breakfast Casserole
This Everything Bagel Vegetarian Breakfast Casserole is an easy breakfast or brunch recipe. All the prep work is done the night before so all you have to do in the morning is pop it in the oven. Super simple. Even though it’s just the two of us Eric and enjoy making a big weekend breakfast or brunch at home. I love casseroles. They are so easy to make and you can do other things while they bake. Plus did I mention the leftovers?!? Leftovers are the best. I love when I make a big weekend meal and I have leftovers for weekdays when I don’t have time to cook.

What Is Everything Bagel Seasoning?
If you love everything bagels raise your hands! I’m a sucker for a good bagel anytime of day. I’m also semi obsessed with Everything Bagel Seasoning (like you buy at Trader Joe’s). It’s a blend of sesame seeds, salt, garlic, onion, and poppy seeds. It’s great sprinkled on avocado toast which is another solid vegetarian breakfast option. If you don’t have a Trader Joe’s near by or to save money you can make your own. Vegan blog It Doesn’t Taste Like Chicken has an easy recipe for Everything Bagel Seasoning.
Breakfast Casserole Serving Ideas
This savory cream cheese packed bagel casserole is incredibly filling on its own. It’s even better when paired with a few complementary sides to round out your morning table.
Here are a few ways to build a complete spread:
- Go Traditional Southern: If you want to lean into comfort food classics, pair a slice of this casserole with smoky vegetarian baked beans, fried green tomatoes, or warm grits.

- The Sweet & Savory Balance: Opposites attract! Balance out the garlic, onion, and poppy seed flavors of the everything bagel seasoning by serving a sweet fruit dish on the side. This easy Lemon Blueberry Croissant Casserole or a warm Cranberry Bagel Breakfast Casserole makes the perfect sweet companion if you’re feeding a larger crowd.
- Double Down on Casseroles: Hosting an effortless brunch where all the prep work is done the night before? Serve this alongside a classic, cheesy Vegetarian Hash Brown Casserole so guests can choose between standard breakfast potatoes or a hearty bagel bake.
- Fresh & Light Additions: To break up the rich cream cheese and egg layers, put out a simple bowl of fresh seasonal berries, sliced avocados drizzled with olive oil, or a bright arugula salad tossed in a lemon vinaigrette.
