For my Friday Favorites pick this week I’m reminding you about these delicious Crustless Breakfast Tarts with Mushrooms that are perfect any time you want a breakfast that’s a bit special! And I think this is a fun breakfast idea to make during the holiday for houseguests, or just as a treat for the family.

This 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 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 breakfast tarts recipe you see here, but I loved the final version of this for a savory breakfast treat!

Now my blog has lots of different ideas for crustless tart recipes inspired by this pan. Of course you can make these breakfast tarts without a fancy pan like mine; keep reading for more about that.

What ingredients do you need for this recipe?

• goat cheese


• half and half


• finely grated Parmesan cheese


• eggs


• Spike Seasoning (affiliate link), or any all-purpose seasoning blend that’s good with eggs

• mushrooms, preferably Cremini mushrooms


• Olive Oil (affiliate link)


• green onions


• grated Mozzarella cheese

What Tart Pan Did I use for the crustless breakfast tarts?

This type of Mini Tart Pan (affiliate link) is what inspired the recipe you see here. (I got my pan from Williams-Sonoma, but they don’t have it any more. The pan that’s linked there from Amazon is very similar to mine.)

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 ONLY a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

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.
