How to Make the Spinach & Mushroom Breakfast Bake
Creating this delectable breakfast bake is straightforward. Follow these steps for a perfect dish every time:
-
Preheat the Oven: Set your oven to 175°C (350°F) and lightly grease an 8×8 inch baking dish. You can use olive oil spray or line it with parchment paper for easy removal.
-
Sauté Onion & Mushrooms: Heat a skillet over medium heat and add the chopped onion and sliced mushrooms along with olive oil and a pinch of salt. Cook for about 5–6 minutes, letting the mushrooms brown slightly for a deeper flavor.
-
Add Spinach to Skillet: Remove the skillet from heat and stir in the chopped spinach. It will wilt quickly, so there’s no need to overcook it.
-
Transfer Veggies to Dish: Spread the sautéed vegetables evenly in your prepared baking dish. Press down lightly to create a flat base for the egg mixture.
-
Whisk Eggs & Cottage Cheese: In a separate bowl, whisk together the eggs, cottage cheese, garlic powder, onion powder, salt, and black pepper. A fork or balloon whisk works great for a smooth blend.
-
Pour Egg Mixture Over Veggies: Carefully pour the egg mixture over the vegetables in the baking dish, tilting the dish gently to ensure it distributes evenly.
-
Add Feta on Top: Sprinkle the crumbled feta cheese over the surface. Using full-fat feta will enhance the texture and flavor.
-
Bake Until Set: Place in the oven and bake for 25–30 minutes until the top is golden and the center is firm. A toothpick inserted in the center should come out clean.
-
Let It Rest: Remove from the oven and let it sit for 10–15 minutes. This resting period helps the bake firm up, making it easier to slice.
-
Slice & Serve: Cut into squares and serve warm or chilled. You can also garnish with fresh herbs or a sprinkle of chili flakes for an extra touch.
How to Serve the Spinach & Mushroom Breakfast Bake
This breakfast bake is versatile and can be enjoyed in different ways. Serve it warm on its own or alongside some fresh fruit for a complete meal. For a brunch gathering, slice into smaller squares and arrange them on a platter. Drizzle with a little olive oil or a splash of balsamic vinegar for extra flavor. If you like a bit of spice, adding red pepper flakes or a dash of hot sauce can also elevate the dish beautifully.
