Eggs: rich in protein and fat, they give structure and creamy richness.
Asparagus: fresh, fibrous, low cal, it’s adds bright green snap and subtle bitterness.
Mushrooms: earthy umami, low calorie, soak up butter and olive oil flavors.
Parmesan: salty, nutty, adds savory punch and melty, slightly grainy richness.
Onion: sweet when caramelized, gives background sweetness and aromatic depth.
Garlic: pungent, small amount lifts everything with warm, savory bite.
Olive oil: healthy fats, helps sauté and adds fruity, peppery notes.
Chives: fresh, mild oniony herb, adds color and subtle bright bite.
Lemon zest: tiny bit brightens flavors, adds citrus lift without sourness.

Ingredient Quantities

8 large eggs

1/4 cup whole milk or half and half

1/2 cup grated Parmesan cheese (or Pecorino)

1 bunch asparagus (about 8 oz)

8 oz mushrooms (cremini or button)

1 clove garlic

2 tablespoons olive oil

1 tablespoon unsalted butter

1 teaspoon kosher salt

2 tablespoons fresh chives or parsley

1 teaspoon lemon zest optional

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 375F. Trim woody ends off the asparagus and cut stalks into 1 inch pieces on the bias. Slice the mushrooms, dice the yellow onion, mince the garlic, grate the Parmesan and chop the chives or parsley. Let the 8 eggs sit at room temp for 10 minutes if you remember, it helps them cook more evenly.

2. In a bowl whisk together the 8 large eggs, 1/4 cup milk or half and half, 1/2 cup grated Parmesan, 1 teaspoon kosher salt, 1/2 teaspoon black pepper and the optional 1 teaspoon lemon zest. Whisk just until combined, dont overbeat or you’ll get big air pockets.

3. Heat an ovenproof 10 inch skillet over medium heat. Add 2 tablespoons olive oil and 1 tablespoon unsalted butter until the butter foams and smells nutty.

4. Add the diced onion and cook 3 to 4 minutes until soft and translucent. Toss in the sliced mushrooms and cook about 5 to 6 minutes until browned and most of their liquid has evaporated. Season lightly as you go.

5. Stir in the asparagus pieces and cook 2 to 3 minutes more so they turn bright green and become crisp tender. Add the minced garlic last and cook about 30 seconds until fragrant, dont let it burn.

6. Spread the veggie mixture evenly across the pan. Pour the egg mixture over the vegetables, tilting the pan so eggs settle around everything. Sprinkle a little extra Parmesan on top if you want a cheesy crust.

7. Cook on the stovetop over medium low for 3 to 5 minutes until the edges are set and the center still jiggles a bit. Resist the urge to stir or poke it.

8. Transfer the skillet to the preheated oven and bake 8 to 12 minutes until the frittata is set and lightly golden on top. If you prefer a brown top, switch to the broiler for 1 to 2 minutes but watch it closely so it doesnt burn.

9. Let the frittata rest 5 minutes so it finishes cooking and slices cleanly. Run a spatula around the edges, slide onto a cutting board, slice into wedges and garnish with the chopped chives or parsley and a little extra grated Parmesan or lemon zest. Serve warm or at room temperature.

Equipment Needed

2. 10 inch ovenproof skillet, cast iron or oven safe nonstick
3. Large mixing bowl
4. Whisk or fork for beating eggs
5. Chef knife
6. Cutting board
7. Box grater or microplane for Parmesan and lemon zest
8. Heatproof spatula to loosen and serve
9. Measuring cups and spoons

FAQ

Q: Can I make this frittata ahead of time? A: Yes. You can bake it, let it cool, then cover and refrigerate for up to 3 days. Reheat in a 325F oven for 10 to 15 minutes or microwave single slices for 60 to 90 seconds. For longer storage freeze wrapped slices up to 2 months, thaw overnight before reheating.

Q: How do I know when the frittata is done? A: The edges should be set and pulling away from the pan, the top slightly puffed and barely jiggles in the center. A thermometer reads about 160 to 165F or a thin knife inserted in the center should come out mostly clean.

Q: Do I have to use whole milk and Parmesan? A: No. Half and half makes it richer, regular milk works fine for a lighter result. You can swap Parmesan for Pecorino, feta, goat or cheddar for different flavor, just taste and adjust salt. For dairy free, use unsweetened plant milk and skip the cheese or use nutritional yeast.

Q: My mushrooms and asparagus make the eggs watery, how do I prevent that? A: Cook the mushrooms until all liquid evaporates and they start to brown, and sauté asparagus until just tender. Drain any excess liquid and cool veggies a bit before adding eggs. Dont add salt too early or veggies will weep more liquid.

Q: Do I need an ovenproof skillet? A: Ideally yes. Cast iron or ovenproof nonstick lets you start on the stove and finish in the oven for a nice top. If you dont have one you can cook low and covered on the stove until set, but the top wont brown like in the oven.

Q: Can I change the veggies or add meat? A: Absolutely. Swap asparagus for spinach, peas or broccolini, add roasted peppers or tomatoes. Cooked sausage, bacon or ham works great too, just make sure any meat is fully cooked before mixing with the eggs.

Spring Asparagus And Mushroom Frittata Recipe Substitutions and Variations

1/4 cup whole milk or half and half: if you dont have either use 1/4 cup evaporated milk or 1/4 cup plain yogurt thinned with 1 to 2 tbsp water, still creamy but yogurt gives a little tang
1/2 cup grated Parmesan cheese: swap for Pecorino Romano, or use grated Gruyere or sharp cheddar (measure the same, Pecorino is saltier so cut back on added salt)
1 bunch asparagus (about 8 oz): replace with broccolini or green beans, or 3 cups baby spinach (saute and squeeze dry before adding)
8 oz mushrooms: use 1 medium zucchini sliced, or 1 cup roasted red peppers, or 1 cup cooked leeks; if you skip mushroom umami, add a splash of soy or a pinch of miso

Pro Tips

1) Dry the mushrooms well before they hit the pan. If theyre wet they steam not brown, and browned mushrooms add way more flavor. Pat them with paper towel or give them a minute in a hot dry pan first.

2) Salt as you go. Season the onions, mushrooms and asparagus lightly while cooking so each layer tastes good. If you only salt at the end the veggies can be bland and the whole frittata suffers.

3) Texture trick: use half cream or half and half for a richer set, but dont overbeat the eggs or youll trap too much air and get big holes. Whisk just enough to mix, not to make foam.

4) Finish gently. If you want a browned top, broil for no more than 1-2 minutes and watch it the whole time. Or bake until just set and let it rest 5 to 10 minutes so it firms up and slices cleanly.

5) Make ahead and reheat smart. Frittata stores well in the fridge for 3 days, reheat at low oven temp 300F until warm so it doesnt dry out, or slice and warm in a skillet for better texture than the microwave.
