How to Make Spinach Mushroom Breakfast Casserole
-
Preheat the oven to 375°F (190°C). This is the perfect temperature for a fluffy and perfectly cooked frittata.
-
Sauté the mushrooms in a large skillet with olive oil over medium heat. Cook until they turn golden brown, about 5-7 minutes, releasing their rich flavor.
-
Add the minced garlic and spinach leaves to the skillet. Stir and cook until the spinach wilts down, which should take about 2-3 minutes; the colorful greens will brighten your dish!
-
Whisk together the large eggs, milk, salt, and black pepper in a bowl. Make sure to get a nice frothy mix that will give your frittata its light texture.
-
Pour the egg mixture over the sautéed vegetables in the skillet. Gently stir to ensure everything is nicely combined and evenly distributed.
-
Crumble the goat cheese over the top of the mixture, letting its creamy goodness meld into the frittata as it cooks.
-
Cook on the stovetop for about 3-5 minutes, or until the edges begin to set. You want the bottom lightly browned for a perfect texture.
-
Transfer the skillet to the preheated oven. Bake until the frittata is fully set, around 20-25 minutes. It should puff up and be golden on top!
-
Remove from the oven and let cool slightly before serving. Garnish with sliced green onions and freshly chopped chives for a fresh touch.
Optional: Serve with a side of toast or a light salad for a complete meal.

Expert Tips for Spinach Mushroom Breakfast Casserole
• Fresh Ingredients: Use fresh spinach and mushrooms for the best flavor. Pre-packaged versions can be convenient but may lack vibrancy.
• Don’t Overcook Eggs: Avoid overcooking the frittata in the oven. It should be just set and still slightly soft in the middle for a creamy texture.
• Customize Cheese: Feel free to experiment with different cheeses like feta or cheddar if goat cheese isn’t your favorite. Each brings its own unique flavor!
• Cut Evenly: For perfect portions, use a sharp knife to cut the frittata into wedges after cooling slightly. This ensures clean slices without crumbling.
• Avoid Soggy Bottoms: Make sure to sauté the mushrooms thoroughly to release excess moisture; this prevents a soggy bottom in your Spinach Mushroom Breakfast Casserole.

Spinach Mushroom Breakfast Casserole Recipe FAQs
What type of mushrooms should I use for the Spinach Mushroom Breakfast Casserole?
Absolutely! I recommend using cremini mushrooms for their rich flavor; however, you can also substitute with button or portobello mushrooms if you prefer. Just ensure they are fresh and firm to the touch, avoiding any with dark spots or sliminess for the best results.
How should I store leftover Spinach Mushroom Breakfast Casserole?
To store your frittata, place it in an airtight container in the fridge for up to 3 days. Make sure it’s completely cooled before sealing to avoid condensation. When you’re ready to enjoy it again, simply reheat individual slices quickly in the microwave, or for a little extra texture, pop it in the oven for about 10-15 minutes at 350°F (175°C).
Can I freeze Spinach Mushroom Breakfast Casserole?
Yes, you can definitely freeze it! I recommend cutting the casserole into individual portions. Wrap each piece tightly in plastic wrap, then in aluminum foil, to keep air out. This way, it can last up to 2 months in the freezer. When you’re ready to enjoy it, allow the slices to thaw in the refrigerator overnight, then reheat in the oven for 15-20 minutes at 350°F (175°C) for best results.
I’m worried about overcooking the frittata. Any tips?
Very understandable! To avoid overcooking, keep a close eye while it’s in the oven. You want it to be just set in the center, which usually takes about 20-25 minutes at 375°F (190°C). If you gently shake the skillet and notice a slight jiggle, it’s just about perfect! Allow it to cool slightly before serving to enhance the creamy texture.
Are there any dietary considerations I should be aware of with this recipe?
Definitely! If you are serving this dish to guests, keep in mind that some may have dairy allergies or intolerance. You can easily substitute the goat cheese with a vegan cheese or nutritional yeast for a dairy-free option. Also, be cautious with added salt if anyone has sodium restrictions; you can always provide extra seasoning options on the side!
What ingredients should I look for to ensure freshness?
For the best flavor, choose vibrant, fresh spinach that feels crisp and doesn’t have dark or wilting leaves. For mushrooms, look for firm caps with a smooth surface and no dark spots. Fresh garlic should be plump and free of sprouts. These quality ingredients will really elevate your Spinach Mushroom Breakfast Casserole!
