When I want a delicious and simple breakfast, I often turn to a frittata. When I want a delicious and simple breakfast that cooks in half the time and contains all the flavors of Springtime, I turn to my Spring Asparagus Frittata, baked in a sheet pan!
I have made hundreds of frittatas, also known as a crustless quiche in my personal and professional life and I don't think I'll ever stop. I usually make mine in a 12 inch cast iron pan, but those can take up to an hour to bake. More and more I choose instead to bake them in a rimmed sheet pan. They cook more evenly, no waiting for the middle to be done, and they bake in less time, bringing breakfast to the table in half the time.
This Spring Asparagus Frittata Recipe is made in a small sheet pan, measuring 9 by 13 inches, and can be cut into 6 or 8 servings. Need to feed more people? Or hungrier people? Double the recipe and bake it in an 18 by 13 pan for just another 10 minutes.

See recipe card below for exact quantities.
Substitutions
This recipe is already gluten-free, but you can also adapt it to other dietary needs.
- Dairy Free - Feel free to substitute your favorite alternative milk for the heavy cream. Oh, and vegan cheese is a thing!
- Low sodium - These Spring vegetables are naturally low in sodium, but just reduce the amount of kosher salt you add when seasoning.
- Vegan - I have not tried it, but a simple internet search shows many ways to veganize a frittata, including using tofu, chickpea flour, and mung beans. You can also use egg substitutes, such as Just Egg.
Variations
The thing I love most about a frittata is that you can make it your own based on what you have in your fridge and pantry! It can truly be a clean-out-the-fridge situation, or try one of these versions:
- Italian - One of the most requested frittatas at the bakery, my Italian Frittata has mozzarella, artichoke hearts, and fresh Italian herbs!
- Everything Bagel- My Smoked Salmon Frittata has all the flavors of a bagel with lox, including red onion, capers, tomatoes, and of course smoked salmon. Amazing!
- DIY - The best frittatas are the ones you come up with on your own. For best results, sauté your vegetables first so that they release all their moisture before adding them to the frittata base. You can even add leftover roasted vegetables for a delicious kitchen clean out!
Equipment: Sheet pans
Sheet pans are the undisputed hero of the kitchen. They are not only good for making crispy bacon in the oven, they are also unbeatable for roasting vegetables, making entire sheet pan dinners, and even sheet pan french toast.
Although I also make traditional cast iron pan frittatas, I now prefer to bake mine on a sheet pan. They cook quicker and more evenly and, since it's just my husband and I now, a small sheet pan is the perfect size for use to have some asparagus frittata for breakfast with roasted potatoes on the side. Later we can have some for lunch, alongside a salad. I can also double this recipe and make more frittata for a crowd, using a large sheet pan.
Instructions
Making this asparagus frittata is incredibly easy, and the shallow pan ensures it cooks quickly without overcooking. To save time, feel free to prep all of your veggies and herbs the night before.
Cooking your vegetables ahead of time is essential. Vegetables release water as they cook, so putting them in raw would leave you with a soggy frittata. It only takes a few minutes, and the delicious flavor and texture make it worth it!
Step 1: Start by removing your asparagus tips and then slicing your asparagus stems, mushrooms, and shallots into pieces about ¼ inch thick and chopping your fresh herbs.
Step 2: In a nonstick pan, saute mushrooms and shallots in a little olive oil until mushrooms are caramelized and shallots are soft and browning. Remove from pan.
Step 3: Add another teaspoon of oil to the same pan. Add diced asparagus to the pan with the sprigs of rosemary and thyme and saute for one or two minutes. Add the English peas and saute another minute.
Step 4: Add in 2 cups of loosely packed spinach and saute until it wilts. Add the asparagus tips and gently mix in to warm them, being careful not to break them.
Step 5: Remove the rosemary and thyme and add back the mushrooms and shallots and mix through. Finally, add in most of your chopped herbs, reserving some to garnish at the end.
Step 6: In a medium bowl, or large measuring cup, whisk together eggs and heavy cream. Add salt and pepper and whisk to combine. Set aside.
Step 7: Arrange the vegetables on the prepared sheet pan. Pour the egg mixture over them, making sure to redistribute all of the vegetables evenly. Crumble and add your Boursin cheese. Finally, add in most of your chopped herbs, reserving some to garnish at the end.
Step 8: Bake at 375°F for 15 to 20 minutes, or until the eggs are set. Garnish with your remaining fresh herbs. Serve warm, room temperature, or cold. Enjoy!

Expert tip: larger frittatas
For this sheet pan asparagus frittata, I cook everything first, add it to the sheet pan, and surround them with a rich egg custard. If you want, you can cook everything in a small oven safe pan, add your eggs, and just pop it straight into the oven. You could even double it for a large sheet pan or 12 inch cast iron pan. Just don't forget the larger frittatas will need a longer cooking time.
Accessorize your eggs - Try putting your frittata in little pie crusts like I did with my Quiche in a Muffin Pan. It's like you made an edible coaster for your eggs!

how much spinach should we have for this? I can see in the instructions it's called for but I cant see an amount in the Ingredients list 😅 thanks in advance!
Cynthia Christensen says
Thanks for pointing out this omission. I don't know how that slipped past me, but I fixed it in the post and the recipe card. I also emailed you separately, just in case you were waiting to cook this! Thank you for the heads up!
nicole says
oooh this was so good! it was a great way to enjoy all the fresh seasonal veggies, and pretty simple to put together. it was even easier to eat a giant slice of it XD we used some oyster mushrooms instead of crimini just because we had them, and had to use dry spices, but the flavor still seemed pretty A+ to me. we also didnt have any of the called for pan types so we used a 9 x 13 glass baking dish, which seemed to work perfectly. we kept an eye on the time just in case it baked differently, but it was still the same for our oven. as a bonus, we had some leftover hollandaise so we spread a bit over top straight from the fridge, and it loosened up perfectly just from the frittata's heat. it was already damn good wtihout it, but you cant go wrong with more hollandaise. yummm!
Cynthia Christensen says
Wow! Sounds like you had everything under control and I’m so glad it worked so well for you! And great tip with the hollandaise sauce
