Easy Beet Casserole – Sweet & Savory 30-Minute Bake

Beet Recipes Casserole is my go-to when I crave something both nourishing and comforting. This dish transforms humble beets into a star, with a creamy, cheesy center and a crispy top that everyone loves.

I remember the first time I made this for my family—they were skeptical of a beet casserole, but after one bite, even my picky eater asked for seconds. It's now a regular on our table, especially in fall when beets are at their peak.

The beauty of this casserole is its simplicity: roast the beets, mix with a savory custard, top with cheese and breadcrumbs, and bake until bubbly. It's a complete side or a light main when paired with a salad.

About the Ingredients

1 1/2 pounds (680g) beets, scrubbed and trimmed

Use a mix of red and golden beets for color. If you can't find fresh, use pre-cooked vacuum-packed beets (drain and skip roasting).

2 tablespoons olive oil

Good quality olive oil adds richness. You can substitute melted butter or avocado oil.

1/2 teaspoon salt

Use kosher salt for even seasoning. Reduce if using salted feta.

1/4 teaspoon black pepper

Freshly ground is best. Adjust to taste.

1 cup (240ml) heavy cream

For a lighter version, use half-and-half or whole milk, but the casserole will be less rich.

2 large eggs

Room temperature eggs blend better. If you need an egg-free version, use 1/4 cup (60ml) unsweetened applesauce.

1 teaspoon Dijon mustard

Adds a subtle tang. Regular yellow mustard works too.

1/2 teaspoon dried thyme

Use 1 1/2 teaspoons fresh thyme if you have it.

1 cup (120g) crumbled feta cheese

Feta gives a salty bite. Substitute goat cheese or shredded Gruyère.

1/2 cup (50g) panko breadcrumbs

Panko gives the crispiest topping. Regular breadcrumbs or crushed crackers work in a pinch.

2 tablespoons chopped fresh dill, for garnish

Optional but adds freshness. Parsley or chives are good alternates.

Tips & Tricks

• Wear gloves when handling beets to avoid stained hands, or use a paper towel to rub the skin.
• Roast beets until a knife pierces easily—this ensures they are tender and sweet.
• Let the casserole rest for 10 minutes after baking to set, making it easier to slice.

Step-by-Step Instructions

1. Preheat oven

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

2. Roast the beets

Place beets on the baking sheet, drizzle with 1 tablespoon olive oil, and rub to coat. Roast for 30-35 minutes until a knife slips in easily. Let cool slightly, then peel and slice into 1/4-inch rounds.

3. Reduce oven temperature

Lower the oven to 375°F (190°C). Grease a 9×13-inch baking dish with the remaining olive oil.

4. Make the custard

In a medium bowl, whisk together heavy cream, eggs, Dijon mustard, thyme, salt, and pepper until well combined.

5. Assemble the casserole

Arrange half of the beet slices in the dish, overlapping slightly. Sprinkle with half of the feta. Repeat with remaining beets and feta. Pour the custard evenly over the top.

6. Add the topping

In a small bowl, toss panko with a drizzle of olive oil (or melted butter). Sprinkle over the casserole.

7. Bake

Bake at 375°F (190°C) for 25-30 minutes, until the custard is set and the top is golden brown. The edges should be bubbly. If you want a deeper color, broil for 2 minutes.

8. Rest and serve

Let the casserole rest for 10 minutes. Garnish with fresh dill and serve warm.

Delicious Variations

Make it vegan

use coconut cream, silken tofu, and vegan cheese; skip the eggs.

• Add cooked quinoa (1 cup) to the custard for extra protein and texture.
• Swap feta for shredded Gruyère and add caramelized onions for a French twist.
