Yummm toasty cheesy goodness!! There aren’t many things better for lunch than a classic grilled cheese sandwich.

I like my Keto Grilled Cheese with Hamburger or Chicken Soup but is super filling, so this sandwich is also excellent all by itself, especially for a quick lunch on the go. You can keep it simple with just cheddar, or spruce up this Keto Grilled Cheese with meat, veggies and/or different types of cheese.

Either way, I hope you love this delicious and easy Keto Grilled Cheese!

  3. You can make it your own by selecting your favourite ingredients or using whatever you happen to have on hand.

Keto Grilled Cheese Ingredients

  • almond flour
  • parmesan cheese
  • baking powder
  • onion powder
  • sea salt
  • grated cheddar cheese
  • olive oil
  • an egg
  • cheese of choice for sandwich
  • mayonnaise
  • meat and/or veggies if desired

How to make a Keto Grilled Cheese

Start by heating a skillet on medium high heat, then slice up the cheese for the sandwich.

Grab a square microwave safe dish and add the almond flour, parmesan, baking powder, onion powder and salt. Give it a whisk then mix in the shredded cheddar cheese. Crack in and egg, add the olive oil and whisk until fully combined.

Bread batter all mixed up, ready to be cooked.

Microwave for 90 seconds then let the bread rest for a few moments to cool.

Bread freshly cooked, still in the square glass container, ready to be flipped out.

Flip the container over so that the bread pops out. You may need to run a knife along the side of it to make sure the edges haven’t stuck to the sides of the container.

Allow the bread to cool for a minute or two. Using some accuracy, slice the bread in half, through the middle, so that you have two thin square slices of bread.

Cooked bread, sliced in half, both slices laying on a cutting board, ready to be fried.

Add 1/2 tbsp butter to the hot skillet, stir it around, then place both slices of bread onto the hot butter. Cook for a couple of minutes until the bread is toasty, then flip them both over. Cover both breads in mayo then lay the cheese on one side.

Two slices of bread on a skillet, both slices covered in mayo and one slice topped with cheddar cheese.

Flip the other bread over top of the cheese so that the mayo side is laying on top of the cheese.

Fry for another minute or so until the bottom of the sandwich is toasty. Flip the sandwich over and cook for another minute or two until the bottom bread is toasty and the cheese is melty.

Expert Tips

After many Keto Grilled Cheese Sandwiches, here is a list of tips and tricks I’ve come up with along the way to help you get the most out of yours the very first time.

  1. Do you like extra melty cheese? I do! It helps to leave your cheese at room temperature for an hour or two so that it is warm. This makes the cheese super melty when you go to make your grilled cheese.
  2. If the bread seems wet after the 90 seconds in the microwave, add an additional 15 seconds to ensure it is cooked all the way through.
  3. Make sure your skillet is nice and hot before adding the butter, then the bread. If it is not hot enough, the bread won’t toast properly, making it soggy and sad. You want the bread to end up with that beautiful deep golden colour.

Keto Grilled Cheese additions

There are some drool worthy ingredients you can add to your Keto Grilled Cheese to give it a flavour boost. Here are some ideas:

Cheese

There are so many different types of cheese out there that would be an excellent option for this grilled cheese. Besides cheddar, I highly recommend you try mozzarella, swiss gruyère, brie, aged cheddar or gouda!

What to pair with Keto Grilled Cheese Sandwiches

Soup! My absolute favourite dish to pair with grilled cheeses sandwiches is definitely soup. Here are my favourites:

Single bowl of ranch cauliflower broccoli salad with bacon and cheese.

Don’t feel like soup? How about a crisp Kale Caesar, loaded with parmesan and cheese crisps? Or a Broccoli Salad with Bacon, Cheddar and Kale? This Ranch Cauliflower Broccoli Salad with Bacon and Cheddar is also an excellent choice.

Don’t have a microwave?

No problem! Well, unless you are hangry, then there could be a problem. You can absolutely make this in the oven, however, your Keto Grilled Cheese won’t be ready in 10 minutes.

Here is how to make it in the oven:

Heat the oven to 350° and spray a square glass (oven safe) container with olive or avocado spray oil. In a bowl whisk the almond flour, parmesan cheese, baking powder, onion powder and salt until combined, then mix in the cheddar cheese.

Whisk in the egg and olive oil until fully mixed then pour into the prepared dish. Bake for 15 minutes, until the egg is cooked all the way through. Continue on with the remaining instructions in the recipe card.

    Can you save if prior to roasting it or does it go bad?

    i enjoyed this very much. Will make it again for sure but minus the onion powder.

  3. 5 stars
    Very yummy, good bread texture and super easy! I didn’t have a glass sandwich size container so I tripled the recipe and used an 8×8 square glass baking dish. This was perfect for making 2 small sandwiches the size of a slice of American cheese.
    Will definitely make it again. Would love to try a keto rye bread version.

  4. Is there anything I can use instead of the mayo? I’m not really a fan of it. Or would it be okay to leave it off?

  5. Your write out says microwave the bread for 90 seconds. Your video says 30 seconds … Which is it?

    • Wow, I have no idea how I messed that one up! It is 90 seconds, not 30. I will change my video, thank you for bringing this to my attention! 😅

  6. Hi, could you post the recipe in grams? I’m from Poland, don’t have measuring cups, and spoons come in different sizes. When I try to follow the recipe my batter comes out very thick and the sandwich won’t come out of the glass dish. I have to help it 😉 It’s still delicious, though.
    Thanks

    • Hey Pawel, I used a converter so hopefully they are accurate for you! Here they are in grams:
      18 g almond flour
      14 g parmesan
      1.2 g baking powder
      14 g cheddar cheese
      13 g olive oil
      7 g butter
      I will say that the mixture should be thick. If you still have troubles you could lightly grease the container with olive oil. I hope it works out for you!

  7. 5 stars
    Delicious!! I’ve been using this bread for other things too. I did a grilled cheese first, then a roast beef sandwich, and over medium eggs on toast! It’s great!
