Spinach Mushroom Breakfast Casserole Cooking Guide
Ready to get cooking? Follow these simple steps for a delicious Spinach Mushroom Breakfast Casserole that will have everyone asking for seconds.
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures the casserole cooks evenly once it’s ready to go in.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced cremini mushrooms and sauté for about 5 minutes, or until they start to brown. Add the minced garlic and continue to cook for another minute, stirring frequently. Once the garlic is fragrant, add the packed spinach leaves. Sauté until the spinach is wilted, which should take about 2-3 minutes. Season with kosher salt and black pepper to taste.
Step 3: Prepare the Egg Mixture
In a large mixing bowl, crack the 18 large eggs and add 1/2 cup of milk. Whisk together until fully combined and slightly frothy.
Step 4: Combine Ingredients
Once the vegetables are cooked, remove them from heat. Stir in the sautéed mushroom and spinach mixture into the egg mixture along with the sliced green onions and 3 ounces of the goat cheese (crumbled). Mix well to combine all the ingredients.
Step 5: Transfer to Baking Dish
Grease your baking dish with a little olive oil or cooking spray to prevent sticking. Pour the egg and vegetable mixture into the prepared baking dish, spreading it evenly.
Step 6: Add Remaining Goat Cheese
Crumble the remaining 1 ounce of goat cheese over the top of the casserole for added flavor.
Step 7: Bake
Place the baking dish in the preheated oven and bake for 35-40 minutes, or until the center is set and the top is slightly golden.
Step 8: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. Garnish with freshly chopped chives, if desired. Cut into squares and serve warm.
What to Use Instead
If you’re looking to customize your Spinach Mushroom Breakfast Casserole, consider these substitutions:
- For a dairy-free option: Use plant-based milk and a dairy-free cheese alternative.
- For a different protein: Swap in cooked sausage or diced ham for added flavor.
- For a different cheese: Feta or ricotta can be used in place of goat cheese for a different taste.
- For a gluten-free option: This recipe is naturally gluten-free, but always check your ingredients.
Avoid These Traps
Creating the perfect Spinach Mushroom Breakfast Casserole is straightforward, but here are some common pitfalls to avoid:
- Overcooking the vegetables: Sauté just until tender to maintain their texture and flavor.
- Underseasoning: Don’t skip on the salt and pepper; they enhance the overall taste of the dish.
- Using stale eggs: Always use fresh eggs for the best results.
- Not letting it cool: Allow the casserole to cool slightly before cutting to ensure clean slices.
