How to Make Mushroom Spinach Baked Eggs

Creating these delicious baked eggs with mushrooms and spinach is surprisingly straightforward, and the result is a comforting, flavorful dish that’s perfect for any meal. I find the best way to start is by preheating the oven, which ensures everything cooks evenly.

Step 1: Begin by melting 2 tablespoons of butter in a 10-inch oven-safe skillet over medium heat. Once melted and shimmering, add the 1 small onion, finely diced, and the 8 ounces of mixed mushrooms, sliced. Cook these, stirring occasionally, until the mushrooms release their moisture and it’s completely absorbed, which usually takes about 10-15 minutes. You’re looking for a nice golden-brown color on the mushrooms.
Step 2: Now, stir in the 2 cloves of minced garlic and the 1 teaspoon of fresh thyme, chopped. Cook for just about a minute more until you can really smell that wonderful garlic and herb fragrance.
Step 3: Pour in half of the broth (1/4 cup) and use a wooden spoon to scrape up any flavorful browned bits stuck to the bottom of the skillet – that’s where so much flavor lives! Let this simmer briefly, then add the remaining 1/4 cup broth and the 1/4 cup heavy cream. Bring the mixture to a gentle boil, then reduce the heat to low and let it simmer for 2-4 minutes to thicken slightly into a luscious sauce.
Step 4: Stir in the 4 ounces of brie, rind removed, cut into small pieces, and the 1/2 cup grated parmesan cheese. Keep stirring until the cheeses are completely melted and the sauce is smooth and creamy. Next, add the 4 ounces of fresh baby spinach and stir gently until it wilts down into the cheesy mixture. Season everything with salt and pepper to your taste.
Step 5: Using your spoon, carefully create four small wells within the creamy mushroom and spinach mixture. Gently crack one egg into each well.
Step 6: Carefully transfer the skillet to your preheated oven, set at 350°F (180°C). Bake for about 5-8 minutes, or until the egg whites are just set and the yolks are still a little runny – or bake longer if you prefer firmer yolks. These baked eggs with mushrooms and spinach are truly delightful when the eggs are perfectly cooked.
Step 7: Remove the skillet from the oven. Enjoy these amazing baked eggs with mushrooms and spinach hot, straight from the skillet. They’re fantastic on their own or served with some crusty bread for dipping into that incredible sauce.

Pro Tips for the Best Mushroom Spinach Baked Eggs

I’ve made this dish countless times, and these little tricks really elevate it to perfection:

Use an oven-safe skillet, preferably cast iron, for even heat distribution and a beautiful presentation.
Don’t overcrowd the skillet with mushrooms; cook them in batches if necessary to ensure they get nicely browned instead of steaming.
Make sure your spinach is well-drained after washing to avoid making the sauce too watery.

Variations of Mushroom Spinach Baked Eggs You Can Try

Once you’ve mastered the classic mushroom spinach baked eggs, there are so many fun ways to switch things up! I love experimenting with this recipe, and here are a few of my favorite twists:

Low Carb Mushroom Spinach Baked Eggs: For a perfectly low carb mushroom spinach eggs option, simply omit the breadcrumbs if you were using them in a different variation, and ensure you’re using a low-carb vegetable broth. The natural low carbohydrate count of the mushrooms, spinach, and eggs makes this a fantastic choice for keto or low-carb diets.
Spicy Kick: Add a pinch of red pepper flakes along with the garlic and thyme in Step 2 of the instructions. This gives a lovely warmth that complements the earthy mushrooms and creamy cheese beautifully.
Sheet Pan Meal: Instead of using an oven-safe skillet, spread the mushroom and spinach mixture onto a baking sheet. Make wells, crack in your eggs, and bake until set. This is a great way to make a larger batch or if you don’t have an oven-safe skillet.
Mushroom and Spinach Egg Cups: For individual servings, prepare the mushroom and spinach mixture as directed, then spoon it into greased muffin tins. Crack one egg into each muffin cup and bake until the eggs are set. These are perfect for grab-and-go breakfasts.
