Southwestern Crustless Breakfast Tarts are perfect for a low-carb or Keto breakfast that’s loaded with southwestern flavors! I like to eat these with a fork with sour cream and salsa, but they’re also great for a grab and go breakfast.

If you’re a regular reader you know that I’m in a constant process of updating and improving the recipes on this site. And recently I worked on this recipe for Southwestern Crustless Breakfast Tarts with Kara, and we loved the improvements to the recipe and the updated photos!

For the updated version we replaced the roasted peppers from a jar with a fresh red bell pepper and a can of diced green chiles. I loved the addition of diced green chiles to this recipe, but if you don’t want that spiciness you can leave those out. I ate them with a dollop of sour cream and some salsa on top, and for me one of these made a perfect low-carb breakfast.

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.)

  • large red bell pepper
  • olive oil
  • canned diced green chiles (affiliate link)
  • green onions
  • sour cream
  • ground cumin (affiliate link)
  • Spike Seasoning (affiliate link) (Or use any all-purpose seasoning that’s good with eggs.)
  • fresh-ground black pepper to taste
  • eggs
  • grated Mexican Blend cheese

What if you don’t have a mini tart pan to make the breakfast tarts?

If you don’t have a Mini Tart Pan (affiliate link) like mine, you can make these in a Jumbo Muffin Pan (affiliate link) for a thicker tart.  The openings in my pan are about 4 inches across, so if your muffin cups are smaller you’ll probably have to increase the baking time just a little.

Can the Southwestern Breakfast Tarts be reheated?

These Southwestern Crustless Breakfast Tarts reheat beautifully in the microwave. You could probably reheat them in a toaster oven too, but I haven’t tried that method.

How to make Southwestern Crustless Breakfast Tarts:

(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. Cut up the red bell pepper into short strips and saute for a few minutes, then add the can of diced green chiles (affiliate link) (with juice) and cook a few minutes more.
  2. Add the pepper mixture and sliced green onions to tart well, and sprinkle each one with a few tablespoons of grated cheese.
  3. Beat the sour cream with a fork until it’s soft.
  4. Then add the spices and beat in the eggs, a few at a time. (Don’t worry about getting the sour cream totally mixed with the egg.)
  5. Pour egg mixture over the veggie/cheese mixture, dividing it evenly.
  6. Take a fork and gently stir so the peppers, green onions, and cheese are well-distributed in the egg mixture.
  7. Bake at 375F/190 about 25-27 minutes, or until tarts are well set and slightly browned on top.
  8. Serve hot, with sliced green onions for garnish and sour cream and salsa to add at the table if desired!

Total Time 42 minutes

Southwestern Crustless Breakfast Tarts are perfect for a low-carb and gluten-free breakfast that’s loaded with flavor!


  • 1 large red bell pepper, seeds and stem removed and cut into short strips
  • 2 tsp. olive oil (more or less, depending on your pan)
  • 1 4 oz. can diced green chiles (see notes)
  • 2 green onions, thinly sliced
  • 1/4 cup sour cream, whisked to soften
  • 1/4 tsp. ground cumin
  • 1 tsp. Spike Seasoning (Or use any all-purpose seasoning that’s good with eggs if you don’t have Spike.)
  • fresh-ground black pepper to taste
  • 6 eggs
  • 3/4 cup grated Mexican Blend cheese


  1. Preheat oven to 375F/190C.  Spray the Mini Tart Pan (affiliate link) or silicone muffin cups (affiliate link ) with non-stick spray or olive oil.
  2. Cut out the stem and seeds from the red bell pepper and cut it into short strips.
  3. Heat the olive oil in a non-stick pan over medium-high heat, add the red peppers, and cook 2-3 minutes, just until they barely start to soften. Then add the can of diced green chiles (affiliate link) and cook about 2 minutes more.
  4. Slice green onions while peppers and chiles are cooking.
  5. Divide the pepper mixture among the tart wells and add a generous pinch of green onion to each one, topped with a generous pinch of grated cheese.
  6. Put the sour cream in a large glass measuring cup (or a bowl with a pour spout) and whisk the sour cream with a fork.  Add the ground cumin, Spike Seasoning (affiliate link), and fresh-ground black pepper and stir to combine.
  7. Then add the eggs two at a time, whisking with the fork between each pair of eggs to combine the yolks and whites and mix the eggs with the sour cream.  (Don’t worry if the eggs and sour cream are not perfectly combined.)
  8. Divide the egg mixture evenly among the tarts, pouring it over the peppers/cheese.  Use a fork to gently stir each one so the cheese, peppers, and green onions are well-distributed in the eggs.
  9. Bake tarts 25-27 minutes, or until the eggs are completely set and the top is starting to get lightly browned.  (If you’re using a muffin pan where the wells are less than 4 inches in diameter, you might have to increase the cooking time a little.)
  10. Serve hot, with a dollop of sour cream and some salsa on top if desired.
  11. These crustless breakfast tarts will keep at least a week in the refrigerator and can be microwaved or reheated in a toaster oven.  (Don’t microwave too long or the eggs will get rubbery.)


I used a lovely tart pan from Williams-Sonoma (that I splurged on when someone gave me a gift certificate) for this recipe. If you don’t have a pan like that, a Jumbo Muffin Pan would make a pretty good substitute.

One can of green chiles (affiliate link) wasn’t much spice, but you can use less than a full can if you’re making for kids or don’t want them spicy.
