These delicious Crustless Breakfast Tarts with Mushrooms are the type of special breakfast treat that’s perfect for the holidays! This fun breakfast tart idea got started when my sister Laurel sent me a generous gift card to William-Sonoma a few years ago as a thank you gift. I went to the Salt Lake William-Sonoma (where my friend Bobbyanne is the manager) and started looking around for something fun. And if you’ve visited Williams Sonoma you know how they have so many inspiring cooking treasures for people who love to cook!

When I spotted a fabulous tart pan that was on sale, I experienced one of those unexplainable flashes of cooking inspiration and my mind went immediately to a custardy egg mixture baked in the shape of a tart. It took me several tries to come up with the recipe you see here for Crustless Breakfast Tarts with Mushrooms, but I loved the final version of this for a savory breakfast treat, and now my blog has Tomato Basil Breakfast Tarts, Asparagus Breakfast Tarts, Cheesy Zucchini Breakfast Tarts, and Southwestern Breakfast Tarts, all inspired by this pan. But I still love these breakfast tarts with mushrooms and goat cheese and these are still the ones I’m most likely to make if I have overnight guests or you can check out Low-Carb and Keto Grab-and-Go Breakfasts for more tasty breakfast recipes like this one.

Of course you can make these breakfast tarts without a fancy pan like mine; keep reading for more about that. Or check out the tart pan the next time you’re in William’s Sonoma; it does go on sale a few times a year. After I post this I’ll be taking a few days off from the blog to go spend Christmas at my sister Val’s house in central Utah. I hope all my readers will enjoy the coming week no matter where you are or what you’re doing to celebrate!

What Tart Pan Did I use for Crustless Breakfast Tarts with Mushrooms?

This is the gorgeous Williams-Sonoma Tart Pan that inspired the recipe.  (For the record, Williams-Sonoma doesn’t know I’m alive and they haven’t sponsored this post.  I’m just providing the link to the pan for anyone who’s interested; I don’t make a dime if you buy the pan.  But I bet you will love it as much as I do, maybe get one as a Christmas gift for yourself?)

Can I make Crustless Breakfast Tarts without a Tart Pan?

Use large muffin cups or individual gratin dishes to bake this delicious mixture of eggs, goat cheese, cream, Parmesan, mushrooms, green onions, and Mozzarella if you don’t want to buy a tart pan.  My breakfast tarts are about 4 1/2 inches across, so if you bake in something smaller you might have to increase the baking time a couple of minutes for a thicker tart.  But if you like mushrooms and goat cheese, I promise that this is a lovely way to start the day!

How to Make Crustless Breakfast Tarts with Mushrooms:

(This is just a summary; scroll down for complete printable recipe, including nutritional information.)

  1. You want the custard mixture to be room temperature when you bake it, so start by letting the goat cheese soften. (Use another type of soft white cheese if you’re not a goat cheese fan.
  2. Slice mushrooms if needed (or buy pre-sliced mushrooms.)
  3. Heat oil in frying pan, then saute the mushrooms until they’re nicely browned (and all liquid has evaporated).
  4. Then divide mushrooms between the 6 tart wells.
  5. When goat cheese is soft, mix in the beaten eggs a little at a time. Season the mixture with the Spike Seasoning and pepper.
  6. Fill the wells in the tart pan with the custard mixture, then sprinkle green onions and grated mozzarella over each.
  7. Bake 25-27 minutes, or until the tops are starting to brown.
  8. Tarts will puff up a little and sink down as they cool.
  9. Serve hot.

Crustless Breakfast Tarts with Mushrooms

Yield 6 servings
Prep Time 30 minutes
Cook Time 27 minutes
Total Time 57 minutes

Crustless Breakfast Tarts with Mushrooms are a delicious meatless breakfast that's perfect to make for a special occasion!

Ingredients

  • 4 oz. goat cheese, crumbled and softened (see notes)
  • 1/4 cup half and half (see notes)
  • 2 T finely grated Parmesan
  • 8 eggs, beaten
  • 1 tsp. any all-purpose seasoning blend that’s good with eggs
  • fresh-ground black pepper to taste
  • 12 oz Cremini mushrooms, washed and sliced (see notes)
  • 2 tsp. olive oil
  • 2 green onions, thinly sliced
  • 6 T grated Mozzarella cheese

Instructions

  1. Remove goat cheese from the fridge, cut off 4 ounces, crumble, and put it in a bowl to start to soften.
  2. Preheat oven to 375F/190C. Spray tart pan (or large muffin cups or gratin dishes) with olive oil or non-stick spray.
  3. Wash the mushrooms and slice about 3/8 inch thick. (Or buy pre-sliced mushrooms, which makes it easy!)
  4. Heat the oil in a non-stick frying pan (use the biggest pan you have so the mushrooms aren’t too crowded.)
  5. Cook mushrooms over medium-high heat until all the released liquid has evaporated and mushrooms are starting to brown, about 10 minutes.
  6. Divide mushrooms between the wells in the tart pan.
  7. When the goat cheese has softened, use a fork to mix half and half into the goat cheese; then mix in the Parmesan.
  8. Beat eggs in a different bowl and then mix about 1/3 of the egg at a time into the goat cheese mixture, stirring each time you add more egg.  (The mixture doesn’t need to be completely smooth.)
  9. Season the mixture with the Spike Seasoning (affiliate link) and black pepper.
  10. Add the custard mixture on top of the mushrooms and gently stir to get mushrooms distributed evenly.
  11. Then sprinkle a generous pinch of green onions on top of each tart, followed by one tablespoon of grated Mozzarella.
  12. Bake 25-27 minutes (or slightly longer if you don’t have this tart pan and your tarts are a little thicker.)
  13. Cook just until the tarts are starting to barely brown on the top; the custard mixture should be soft. Serve hot.

Notes

Use the type of goat cheese that comes in a log. You can use milk or heavy cream instead of half and half if that's what you have. I used Spike Seasoning (affiliate link) for this recipe. I loved this with brown Cremini mushrooms, but regular white mushrooms would also be fine.

These breakfast tarts will keep in the fridge for at least a week and can be reheated in a microwave or hot toaster oven.  (It only takes just over a minute in my microwave; don’t microwave too long or the eggs will get rubbery.)

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Crustless Breakfast Tarts with Mushrooms and Goat Cheese are perfect for low-carb or Keto diets. The tart has low-glycemic ingredients and goat cheese is relatively low in fat, but the South Beach Diet would recommend using low-fat milk and Mozzarella for this recipe. With those cautions, I think this would be great for any phase of South Beach.

  1. What is the measurement 'T' in your recipe please? – teaspoon, tablespoon etc

  2. Beth I'm not sure how the Feta will mix in but I think softened cream cheese or even sour cream could work.

  3. I love the idea of these, but I do not like goat cheese. I usually substitute out in recipes, but this one is unique in that you are mixing it with the liquids to make a custard. Any suggestion on a substitute? Feta? I would make these in a heartbeat otherwise!

  4. Thanks Laurel; so glad you enjoyed it!

  5. This was wonderful. Once again, Kalyn, you do not disappoint with a great breakfast recipe. I loved the creaminess of the goat cheese and eggs + spike is one of my favorite combinations.

  6. Anne, I can't say enough good about the pan, you will love it!

  7. Oh wow, I love the sound of this recipe, but gotta say – also covet that pan! I've always used the little individual ones – having them all in one pan is brilliantly practical. Adding to Santa's list . . .

    — Anne

  8. Thanks Bill! The pan was definitely an investment but I think I'm going to use it a lot.

  9. I love these tarts, Kalyn! Such a great way to start the morning. I've got to get one of these tart pans, too! Great post!

  10. Thanks Joanne! One of these tarts is a perfect breakfast for me.

  11. What a super cute tart pan! I have never seen one of those but will have to have one. The mini breakfast tarts sound delicious! perfect for on-the-go breakfasts.

  12. Pam, I am late to the Tart Pan Fan Club, but I plan to make up for lost time!

  13. I do have a cute tart pan, and that was the first thing I thought of when I saw this in the thumbnail!

  14. Emm, I only mean that it's hard to mix the eggs, goat cheese, and parmesan to a smooth consistency if the goat cheese isn't soft. But if you don't mind chunks of goat cheese through out the mixture it will be fine. I do think the dish will have a more custardy texture if the ingredients are mixed better though.

    Thanks Dara. I think there are a lot more tarts in my future!

  15. These are just so pretty, Kalyn! That tart pan was the perfect splurge.

  16. You say "It's important to let the goat cheese soften and then mix in the beaten eggs a little at a time." Can you tell me why it's important? The eggs aren't whipped like whites are so I am puzzled. Thank you for the recipe!!

  17. What you're describing sounds like what I call Egg Muffins. I've been making those since about 2005, but the texture of these tarts is more like a custard. Both are delicious, but these Breakfast Tarts are a little richer and I love the look of the scalloped edges. So many fun things to do with eggs, right?

  18. I make something similar using a cupcake tray all the time! Except I don't sautee the mushrooms before hand – I just chop as many veggies as I'd like (usually peppers, mushrooms & spinach) and then pour a beaten egg on top.

  19. Lydia, my thoughts exactly!

  20. That's a lovely tart pan! And who needs crust when you can have a whole "tart" made of filling?!
