Recently my sister Laurel gave me a very generous gift card for William-Sonoma, a store that’s always a wonderful splurge for me.  (Thanks Laurel!)  So I went to the Salt Lake William-Sonoma (where my friend Bobbyanne is the manager) and started looking around for something fun.  They happened to be having a sale on bakeware, and when I spotted a fabulous tart pan 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 several tries to come up with these delicious Crustless Breakfast Tarts with Mushrooms and Goat Cheese, but I loved this for a savory breakfast treat, and I can tell the new tart pan will be inspiring more interesting egg dishes.

But what if you don’t want to buy a special tart pan just to make this dish?  Use large muffin cups or individual gratin dishes to bake this delicious mixture of eggs, goat cheese, cream, Parmesan, mushrooms, green onions, and Mozzarella.  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.  If you like mushrooms and goat cheese, I promise that this is a lovely way to start the day!

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 Santa can bring one?)

You want the custard mixture to be room temperature when you bake it, so make that first.  It’s important to let the goat cheese soften and then mix in the beaten eggs a little at a time. Season the mixture with the Spike Seasoning and pepper.

Saute the mushrooms until they’re nicely brown (and all liquid has evaporated) and then divide mushrooms between the 6 tarts.

Fill the wells in the tart pan with the custard mixture, then sprinkle green onions and grated mozzarella over each.  Bake 25-27 minutes, or until the tops are starting to brown.

Tarts will puff up a little and sink down as they cool.  Serve hot.

Crustless Breakfast Tarts with Mushrooms and Goat Cheese

Crustless Breakfast Tarts with Mushrooms and Goat Cheese are a delicious meatless breakfast!


  • 4 oz. goat cheese, crumbled and softened (Use the type of goat cheese that comes in a log.)
  • 1/4 cup milk, half and half, or cream
  • 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 Crimini (Baby Bella) mushrooms, washed and sliced
  • 2-3 tsp. olive oil (depending on your pan)
  • 2 green onions, thinly sliced
  • 6 T grated low-fat Mozzarella cheese


  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.
  3. Spray tart pan (or large muffin cups or gratin dishes) with olive oil or non-stick spray.
  4. When the goat cheese has softened, use a fork to mix the milk, half and half, or cream into the goat cheese; then mix in the Parmesan.
  5. 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.)
  6. Season the mixture with the Spike Seasoning and black pepper.Wash the mushrooms and slice about 3/8 inch thick.
  7. Heat the oil in a non-stick frying pan (use the biggest pan you have so the mushrooms aren’t too crowded.)
  8. Cook mushrooms over medium-high heat until all the released liquid has evaporated and mushrooms are starting to brown, about 10 minutes.
  9. Divide mushrooms between the wells in the tart pan.Add the custard mixture on top of the mushrooms and gently stir to get mushrooms distributed evenly.
  10. Then sprinkle a generous pinch of green onions on top of each tart, followed by one tablespoon of grated Mozzarella.
  11. Bake 25-27 minutes (or slightly longer if you don’t have this tart pan and your tarts are a little thicker.)
  12. Cook just until the tarts are starting to barely brown on the top; the custard mixture should be soft.
  13. Serve hot.


I used Spike Seasoning for this recipe.

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. I LOVE this recipe!! I’ve adapted it to several different variations. Hubby’s favorite was the spinach/mushroom/bacon with swiss cheese. Thank you, Kalyn, for providing great recipes (and the inspiration for more).

  2. These are awesome! I made with a few changes. I added sauted onions, publano pepper (I needed to use it up) and a red pepper. Also some pork sausage (2/3#) I warmed the goat cheese in the micro (2 min@power 2) , stirred in the half ‘n half then added all to the eggs at one time. I used a silicon muffin tray., putting in the veggies and meat first then filling with the egg and cheese mixture. Baked at 375 as instructed and love the result! Thanks for sharing this as it is on my “make again” list!

  3. Even my picky 5 1/2 year old said, “I don’t ‘LIKE’ it, I LOVE it!!” even wanted seconds 🙂 My husband I were both pleasantly surprised.. I made this in an 8″ Emile Henrie and also a 5 inch square stoneware baking dish for the “overflow” so just goes to show how flexible your recipes are. We’re thinking of adding asparagus, next time. although I have a feeling your original recipe will be preferred. Thanks, again!! <3

  4. I don't use store bought mixed spices, they usually contain more salt than I would use. I'm fortunate enough to be close to a spice store that mixes all their own blends, many without salt. To make up for less salt in this recipe I substituted Feta Cheese for the goat cheese. Between the Feta and Parmesan that was more than enough salt for me. The rest of the recipe was very good and I'll be making this again.

  5. Did I miss where and when you're supposed to add the Spike seasoning and pepper? This is probably a no-brainer for most cooks, but I need directions down to the nth teaspoon. Thanks.

    • No my bad on that, I left it out completely. You could either add to the goat cheese mixture (my preference) or season the mushrooms with it. I will edit the instructions, thanks!

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

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

  8. 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!

  9. Thanks Laurel; so glad you enjoyed it!

  10. 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.

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

  12. 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

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

  14. 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!

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

  16. 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.

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

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

  19. 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!

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

  21. 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!!

  22. 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?

  23. 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.

  24. Lydia, my thoughts exactly!

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