Baked Mini-Frittatas with Mushrooms, Cottage Cheese, and Feta found on KalynsKitchen.com

If you’ve been reading this blog for a while, you probably noticed how I love to make little breakfast tarts or mini frittatas with my favorite Mini Tart Pan (affiliate link). And when I decided to update the photos for these Mushroom Tarts with Feta, I couldn’t resist using that tart pan to make them a bit fancier.

But these are really just a slightly bigger and flatter version of the Egg Muffins that have been so popular on the blog, and if you don’t want to buy a tart pan you can make them in my favorite silicone muffin cups (affiliate link), and just cook a few minutes longer for the thicker version.

This is something I’d eat with a fork, maybe with a dollop of sour cream. And these mini crustless tarts have lots of mushrooms and cheese for a baked egg dish that’s a fairly dense in texture and high in protein. And I have been loving this recipe for a few years now, so today I’m reminding you about it for my Friday Favorites pick this week; hope you will try it!

What ingredients do you need for this recipe?

(This is only a list of ingredients; 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.)

  • mushrooms (I used brown Cremini mushrooms, also called Baby Bellas)
  • Olive Oil (affiliate link)
  • cottage cheese
  • crumbled Feta Cheese
  • green onions
  • eggs
  • Spike Seasoning (affiliate link)or any type of all-purpose seasoning blend that’s good with eggs
  • fresh-ground black pepper to taste

What pan did I use to cook the Mushroom Tarts with Feta?

The Mini Tart Pan (affiliate link) I’m so infatuated with is perfect for these mushroom tarts. Of course if you don’t want to buy a fancy tart pan, these can certainly be made in large silicone muffin cups (affiliate link), a regular large muffin pan, or any kind of individual large ramekins or little tart pans, and they might be just slightly different sized than the ones I made. But if you do decide you want the pan (which I love) search “tart pan” on my site for lots more ideas for what to make with it.

How low in carbs are these Mushroom Tarts with Feta?

This tasty breakfast treat only has 4 net carbs in one tart, so even if you eat two at a time it’s not much of a splurge on carbs!

How to make Mushroom Tarts with Feta:

  1. Preheat the oven to 375F/190C. SprayMini Tart Pan (affiliate link) or silicone muffin cups, Jumbo size (affiliate link) with non-stick spray or mist with olive oil.
  2. Rinse cottage cheese in a fine-mesh strainer and let it drain while you cook mushrooms until they’re slightly browned and all the water has evaporated.
  3. Put mushrooms in the tart pans or silicone baking cups.
  4. Then put the drained cottage cheese, crumbled Feta, and sliced green onions on top of the mushrooms.
  5. Beat the eggs with the pepper and Spike Seasoning (affiliate link) and pour over the mushrooms. (I like to stir gently with a fork so everything is well-combined.)

Mushroom Tarts with Feta

Prep Time 15 minutes
Cook Time 25 minutes
Total Time 40 minutes

Mushroom Tarts with Feta are great for a meatless breakfast idea, and these are perfect to make on the weekend and reheat during the week! And these savory crustless mushroom tarts would also be great for an appetizer.

Ingredients

  • 12 oz. mushrooms washed and sliced (I used brown Cremini mushrooms, also called Baby Bellas)
  • 2 tsp. olive oil (or more, depending on your pan)
  • 1/2 cupย  cottage cheese, rinsed and drained well
  • 3/4 cup crumbled Feta Cheese
  • 3 T thinly-sliced green onions
  • 6 eggs, beaten
  • 1/2 tsp. Spike Seasoning (or use any type of all-purpose seasoning blend that's good with eggs)
  • fresh-ground black pepper to taste

Instructions

  1. Preheat the oven to 375F/190C. Spray Mini Tart Pan (affiliate link) or 6 Jumbo Muffin Cups (affiliate link) with non-stick spray. (Or use any type of extra-large muffin cup or small ramekins, but the silicone cups will keep the egg mixture from sticking more than other types of dishes.)
  2. Put the cottage cheese into a fine colander and rinse with cold water until only the curds remain. Let the cottage cheese drain while you cook the mushrooms.
  3. Wash the mushrooms in a colander and blot dry with paper towels. Slice mushrooms into thick slices.
  4. Heat the olive oil in a large non-stick frying pan over medium-high heat and cook mushrooms until they release all their liquid and it has evaporated and the mushrooms are lightly browned, about 6-8 minutes. Put the mushrooms into the bottom of the tart pan wells or baking cups.
  5. Crumble the feta cheese and thinly slice the green onions. Layer the cottage cheese, feta, and green onions on top of the mushrooms.
  6. Beat the eggs with Spike Seasoning (affiliate link) and black pepper, and divide eggs among the tart pan wells or muffin cups. Take a fork and gently "stir" the mixture so all the other ingredients are coated with egg.
  7. Bake the mini-frittatas about 25 minutes, or until they are set and lightly browned on top.
  8. Serve hot, with a dollop of low-fat sour cream if desired.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
These easy Mushroom Tarts are loaded with high protein low-carb ingredients and would be approved for low-carb and Keto diets and all phases of the original South Beach Diet. They do have a generous amount of cheese, so if you’re following South Beach and actively trying to lose weight, I’d limit the serving size to one mini-frittata for a meal.
