Cooking Instructions

Step 1: Prepare Your Veggies and Get the Pan Ready

The first step to a fantastic frittata is to get all your ingredients prepped and ready to go. This is a dish that moves fairly quickly once the eggs are involved, so having everything chopped and measured will make the process smooth and enjoyable. Dice your yellow onion into small, uniform pieces. This ensures they cook evenly and become sweet and tender. Chop your baby spinach; a rough chop is perfectly fine. Slice your cherry tomatoes in half. This releases their juices as they cook, adding a lovely burst of sweetness and acidity. Slice your mushrooms; cremini or button mushrooms are excellent choices, but feel free to use your favorites.

Now, let’s get your oven ready. Preheat your oven to 375°F (190°C). You’ll also need an oven-safe skillet, preferably one that’s about 10 inches in diameter. Cast iron skillets are ideal for frittatas because they conduct heat evenly and can go from stovetop to oven seamlessly. If you don’t have an oven-safe skillet, you can always cook the initial ingredients on the stovetop and then transfer the mixture to a greased baking dish before adding the eggs.

Step 2: Sauté the Aromatics and Mushrooms

Place your oven-safe skillet over medium heat. Add a tablespoon of olive oil or your preferred cooking fat. Once the oil is shimmering, add the diced yellow onion. Sauté the onion for about 5-7 minutes, stirring occasionally, until it becomes softened and translucent. We’re not looking for browning here, just gentle cooking to release its sweetness.

Next, add the sliced mushrooms to the skillet. Increase the heat slightly to medium-high. Cook the mushrooms, stirring frequently, for about 5-8 minutes, or until they release their moisture and begin extract to turn golden brown. Mushrooms have a high water content, so this step is crucial to develop their rich, earthy flavor and prevent a watery frittata. Don’t overcrowd the pan; if necessary, cook the mushrooms in batches to ensure they brown properly rather than steam. Once the mushrooms are nicely browned, add the halved cherry tomatoes to the skillet. Cook for another 2-3 minutes, just until they start to soften and release some of their juices.

Step 3: Wilt the Spinach and Prepare the Egg Mixture

Now it’s time to add the spinach. Toss the chopped baby spinach into the skillet with the other vegetables. Stir gently until the spinach wilts down, which will only take a minute or two. The heat from the pan will be enough to do the trick. Once the spinach is wilted, remove the skillet from the heat. This is important because we don’t want the vegetables to continue cooking while we prepare the egg mixture.

In a medium bowl, crack your 8 large eggs. Add the heavy cream (or your chosen dairy alternative like Greek yogurt or sour cream, which will add a lovely tang). Whisk the eggs and cream together until they are well combined and slightly frothy. Now, it’s time to season. Add the ground mustard, garlic powder, salt, and ground black pepper to the egg mixture. The ground mustard might seem unusual, but it adds a subtle tang and depth that complements the mushrooms beautifully. Whisk everything together again until all the seasonings are evenly distributed.

Step 4: Combine and Cook the Frittata

Pour the seasoned egg mixture evenly over the vegetables in the skillet. Make sure to distribute the vegetables so they are mostly submerged in the egg mixture. Gently shake the pan to help the egg mixture settle. Sprinkle the shredded mozzarella cheese (or your alternative cheese) evenly over the top of the frittata. The cheese will melt and create a delicious, gooey topping.

Carefully transfer the skillet to the preheated oven. Bake for 20-25 minutes, or until the frittata is set in the center and the top is golden brown. To check for doneness, you can gently insert a knife or a toothpick into the center of the frittata. If it comes out clean, your frittata is ready. The edges should be slightly puffed and firm, and the cheese should be melted and bubbly.

Step 5: Rest and Serve Your Delicious Frittata

Once the frittata is cooked, carefully remove the skillet from the oven. It will be very hot, so use oven mitts and exercise caution. Let the frittata rest in the skillet for about 5-10 minutes before slicing. This resting period allows the frittata to firm up completely, making it much easier to cut into neat wedges. If you try to slice it too soon, it might be a bit too soft and could fall apart.

After resting, you can either slice it directly in the skillet or carefully invert it onto a serving platter if your skillet has handles that make this awkward. Serve your Mushroom Frittata warm. It’s absolutely delightful on its own, or you can pair it with a simple side salad for a complete meal. Leftovers can be stored in the refrigerator for up to 3 days and are delicious served cold or gently reheated. Enjoy this wholesome and flavorful frittata!

Frequently Asked Questions:

Can I make this mushroom frittata ahead of time?

Absolutely! A mushroom frittata is perfect for making ahead. You can bake it, let it cool completely, and then store it in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in a low oven or microwave until warmed through.

What kind of mushrooms work best for this frittata?

While cremini mushrooms are a fantastic and readily available choice, feel free to use a mix! Shiitake, oyster, or even wild mushrooms will add a more complex and earthy flavor profile to your frittata. Just ensure they are cleaned and sliced appropriately.

My frittata is sticking to the pan. How can I prevent this?

Ensuring your pan is well-seasoned or properly greased is key. Using a good quality oven-safe non-stick skillet is highly recommended. Also, make sure the pan is fully heated before adding your ingredients. If you’re really concerned, you can bake it in a greased pie dish or a small cast-iron skillet.
