A Sweet Taste of Nostalgia – The Story Behind Mediterranean Brunch Casserole
Brunch has always held a special place in my kitchen—it’s the perfect time to slow down, gather loved ones, and enjoy something comforting yet fresh. This Mediterranean Brunch Casserole brings that feeling together in a single dish. It’s a low-carb, gluten-free twist on traditional egg casseroles, packed with vibrant vegetables, savory sausage, and tangy feta cheese.
I love how the flavors layer—soft spinach, creamy eggs, bursts of tomato, and the salty punch of Parmesan on top. When it bakes, the aroma fills the house with hints of garlic, Italian herbs, and warm, toasty cheese. This casserole reminds me of those Sunday mornings when I’d linger over breakfast with a coffee, the sunlight streaming through the kitchen window, feeling cozy and content.
What You’ll Need to Make These Sparkling Citrus Treats
Here’s a clean list of everything you need to assemble this vibrant casserole. Choosing quality ingredients makes a noticeable difference, especially with fresh vegetables and cheeses.
Ingredients:
Savory Base:
- ½ lb mild Italian sausage (zero-carb if possible)
- ⅓ medium yellow onion, diced
- 2 oz mushrooms, sliced
- ½ tsp minced garlic
Green & Tangy Layer:
- 2 cups fresh baby spinach leaves
- 5 oz feta cheese curds (or crumbled feta)
Egg Custard:
- 6 large eggs
- 1 tbsp tomato paste
- ½ tsp Italian seasoning
- ¼ tsp salt (adjust to taste)
- ¼ tsp black pepper
Finishing Touches:
- 3 leaves fresh basil, sliced thin
- 1 Roma tomato, thinly sliced (9 pieces)
- ¼ cup shredded Parmesan cheese
Preparing Your Oranges for Perfect Candying
Before baking, prep is key. Preheat your oven to 375°F (190°C) and lightly grease an 8×8-inch baking dish. Browning the sausage first creates a rich, savory base that adds depth to every bite. In a skillet over medium-high heat, cook the sausage until golden, then add onions and mushrooms. Let them soften and caramelize slightly, about 5–7 minutes. Stir in the garlic for just a minute to keep it fragrant but not bitter.
Transfer this mixture evenly into your baking dish. It already smells incredible at this stage—the combination of sausage, onion, and mushrooms is the kind of aroma that makes the kitchen feel cozy and inviting.
Crafting the Syrup – The Secret to a Glossy Finish
In this casserole, the “syrup” equivalent is the egg custard, which binds everything together while keeping the dish light and fluffy. Whisk together eggs, tomato paste, Italian seasoning, salt, and pepper until smooth. Pour this evenly over the spinach and feta layers, gently pressing down any pieces of spinach that stick out. I like to pause here and admire the vibrant green of the spinach against the creamy custard—simple yet beautiful.

Once the custard is in place, it’s time to finish assembling. Scatter thinly sliced basil leaves over the top, arrange the tomato slices decoratively, and sprinkle with Parmesan cheese. This final touch adds fragrance, color, and a subtle crispiness as it bakes.
Bake the casserole in your preheated oven for 30 minutes, or until the center is set and the top turns a lovely golden brown. I love watching the transformation—the edges puff slightly, the top becomes lightly caramelized, and the kitchen fills with a warm, herbaceous aroma that’s hard to resist.
Tips for Even Cooking and Preventing Bitterness
- Check the custard early. Oven temperatures vary, so peek after 25 minutes to avoid overbaking.
- Avoid overcrowding the skillet. When cooking sausage and vegetables, a crowded pan will steam instead of brown.
- Adjust seasoning to taste. Feta and Parmesan add saltiness, so taste before adding extra salt.
- Vegetable prep matters. Mushrooms and onions release moisture; cook them until slightly caramelized to avoid soggy casserole.
These small tips help ensure a perfect texture and balanced flavor every time.
Coating and Drying – Achieving That Signature Crystallized Crunch
The finishing touches in this casserole—basil, tomato, and Parmesan—serve a similar purpose as the sugar coating in candy. They create texture and visual appeal, ensuring every bite has complexity and that satisfying “wow” factor. Once baked, let the casserole rest 5–10 minutes. This step is crucial; it allows the custard to set fully, making it easier to cut clean squares without the layers collapsing.
Serving and Storing Your Homemade Orange Candy
Cut the casserole into nine squares and serve warm. I love how each piece shows the colorful layers of spinach, feta, and tomato. Pair it with a light salad, a dollop of Greek yogurt, or enjoy on its own for a hearty brunch.
Store leftovers in an airtight container in the fridge for up to four days. Reheat gently in the oven or microwave—just enough to bring back that soft, custardy texture. This casserole also freezes well in individual portions, making it perfect for meal prep or busy mornings.
Creative Ways to Use Candied Oranges in Desserts and Gifts
While the Mediterranean Brunch Casserole shines on its own, you can mix things up by trying different proteins, cheeses, or vegetables. Omit the sausage for a vegetarian version, or swap in goat cheese, mozzarella, or ricotta. Add-ins like bell peppers, zucchini, olives, sun-dried tomatoes, or asparagus bring new flavors and textures, keeping the dish exciting week after week.
Variations to Try – From Lemon Slices to Chocolate-Dipped Twists
Protein variations are easy—try hot sausage, bacon, ham, chorizo, or even ground turkey. For a make-ahead version, cook the base a day prior, assemble the casserole, and bake when ready. You can also freeze portions for later; it reheats beautifully while retaining flavor and texture. Small tweaks like these allow you to customize the casserole for any occasion or dietary preference.
