Mushroom Frittata
A frittata is one of those magical dishes that feels both rustic and elegant, perfect for a leisurely weekend brunch or a quick weeknight dinner. It’s incredibly forgiving, allowing you to adapt it with whatever vegetables you have on hand. This Mushroom Frittata is a particular favorite of mine, packed with earthy mushrooms, vibrant tomatoes, and melty cheese.

The beauty of a frittata lies in its simplicity – a savory egg custard baked until puffed and golden, studded with delicious fillings.

Cooking Instructions
Prep and Sauté the Vegetables
The first step to a delicious frittata is to build a flavorful base. We’ll start by sautéing our aromatic vegetables. Grab a 10-inch oven-safe skillet (cast iron works beautifully here!) and heat a tablespoon of olive oil or butter over medium heat. Once the oil is shimmering or the butter is melted and slightly foamy, add your diced yellow onion. Cook the onion, stirring occasionally, until it begin extracts to soften and turn translucent, which should take about 5-7 minutes. You’re not looking for browning here, just a gentle softening to release its sweetness. Next, add your sliced mushrooms to the skillet. Continue to cook, stirring, until the mushrooms release their moisture and start to turn a lovely golden brown. This will take another 5-8 minutes. The mushrooms will shrink significantly as they cook, intensifying their flavor. Finally, toss in your halved cherry tomatoes and cook for just a minute or two, until they start to soften slightly. Remove the sautéed vegetables from the skillet and set them aside on a plate. Don’t wipe out the skillet just yet; there will be delicious flavor left in it.
Prepare the Egg Mixture
While the vegetables are cooling slightly, it’s time to get our egg mixture ready. In a medium bowl, crack your 8 large eggs. Whisk them vigorously until the yolks and whites are thoroughly combined and you see a pnon-alcoholic ale yellow color. This incorporates air, which will help the frittata puff up nicely. Now, pour in your ½ cup of heavy cream. If you prefer a tangier flavor or a lighter frittata, you can substitute with ½ cup of plain Greek yogurt or sour cream. Whisk this in until it’s fully incorporated into the eggs. Next, we’ll add our seasonings. Stir in the ½ teaspoon of ground mustard, ½ teaspoon of garlic powder, ½ teaspoon of salt, and ¼ teaspoon of ground black pepper. The ground mustard might seem a bit unusual, but it adds a subtle depth of flavor that complements the mushrooms beautifully. Give it all a final whisk to ensure everything is evenly distributed.
Assemble and Bake the Frittata
Now it’s time to bring it all together. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). If your skillet has any excess oil or butter from sautéing, you can carefully pour most of it off, leaving just a thin coating. Return the skillet to medium-low heat. Pour about half of the egg mixture into the warm skillet. Let it cook undisturbed for about 1-2 minutes, just until the edges begin extract to set. This initial cooking on the stovetop helps to form a base for the frittata and prevents it from sticking. Now, evenly scatter the sautéed vegetables over the partially set eggs. Sprinkle the ½ cup of shredded mozzarella cheese (or your chosen alternative) over the vegetables. Finally, gently pour the remaining egg mixture over the vegetables and cheese, ensuring everything is covered.
Finish Cooking in the Oven
Carefully transfer the skillet to your preheated oven. Bake for approximately 20-25 minutes, or until the frittata is puffed up, golden brown around the edges, and the center is set. You can check for doneness by gently shaking the skillet; the center should be firm and not jiggle excessively. If you’re unsure, you can insert a thin knife or toothpick into the center; it should come out clean. The oven time can vary depending on your oven and the depth of your skillet, so keep an eye on it. If the top is browning too quickly before the center is set, you can loosely tent it with aluminum foil.
Rest and Serve
Once your frittata is perfectly cooked, carefully remove the skillet from the oven. It’s important to let the frittata rest for at least 5-10 minutes before slicing and serving. This resting period allows the frittata to firm up further, making it easier to cut and preventing it from falling apart. The residual heat will continue to cook it slightly. You can serve this delicious Mushroom Frittata warm, directly from the skillet, or let it cool a bit more. It’s fantastic on its own, or served with a simple side salad and some crusty bread. The combination of tender eggs, earthy mushrooms, sweet tomatoes, and gooey cheese is simply irresistible, and it’s a dish that always brings smiles to the table. Enjoy!

Frequently Asked Questions:
Q: Can I make this Mushroom Frittata ahead of time?
Absolutely! Frittatas are excellent for making ahead. Once cooled, you can store it in an airtight container in the refrigerator for up to 2-3 days. Reheat gently in a low oven or microwave until warmed through. It’s perfect for meal prepping!
Q: What kind of mushrooms work best in this frittata?
A variety of mushrooms will work beautifully. I find a mix of cremini and shiitake mushrooms offers a great depth of flavor and texture. However, button mushrooms or even wild mushrooms like oyster mushrooms are also fantastic choices.
Q: My frittata is a bit watery. What did I do wrong?
This can sometimes happen if the mushrooms release too much moisture. Make sure to sauté your mushrooms until they have released most of their liquid and are nicely browned before adding them to the egg mixture. This step is crucial for a perfectly cooked frittata.
