Low-Carb Quick Grilled Cheese Sandwich (keto, primal, grain-free)

There is nothing quite so satisfying as picking up a big, melty slice of grilled cheese sandwich and biting into that melty goodness. Especially when it's low-carb!

I thought these days were behind me, until I discovered 90 second bread. Now, I just want to make up for lost time by eating a different grilled cheese sandwich every day. I have included some of my favourite variations below. Enjoy!

Extra tip from a reader: substitute part of the almond flour with flax meal for a better flavour and no eggy taste.

If you have time to make a whole loaf of low-carb bread, apart from our 90-second bread you can use our Ultimate Keto Bread, Soul Bread or Fluffy Grain-Free Sunflower Bread.

Optional variations (use instead of the above filling):

  • 2 tbsp Red Eye Bacon Jam, 2-3 slices Brie cheese and handful of spinach
  • 3-4 oz cooked chicken, 1/4 sliced avocado, 1-2 slices Jarlsburg cheese
  • 1-2 slices Pastrami, 3-4 slices Provolone cheese and 2 slices red onion

Step-by-step

  1. Place all of the bread ingredients into a small bowl and mix well.

  2. Grease a ramekin, or like me find a bread-shaped storage container. Pour the mixture into the container and shake to distribute evenly.

  3. Microwave on high for 90 seconds. Turn out and cool on a rack.
    Note: If you don’t have a microwave, you can use the oven. Preheat to 175 °C/ 350 °F and bake for 12-15 minutes or until cooked through.

  4. When cool, cut in half and spread with butter, if desired. Place the cheese slices in the middle and toast for approx. 5 minutes (or try any of our suggested variations in the post intro). You can toast it in a frypan, in a panini maker or under a broiler.

    The instructions say….”When cool, cut in half and spread with butter, if desired. Place the cheese slices in the middle and toast for approx. 5 minutes”
    I assume this is done in a frying pan, not in a toaster?

    1. Martina @ KetoDietAuthor

      Hi Lorraine, you could use either pan or a toaster (or even a broiler) although if you use a toaster, the sandwich has to be laying flat so the type of toaster I'd use is closer to a panini maker. Thank you, I'll clarify this for others.

  2. Kevin

    This is absolutely amazing!

    1. Martina @ KetoDietAuthor

      Thank you, glad you enjoyed!

    Does the baking powder have to be gluten free?

    1. Martina @ KetoDietAuthor

      That only depends on your dietary preferences. The recipe will work just as well with regular baking powder, although I recommend avoiding gluten if you follow a low-carb/keto diet.

  4. Susan

    Is there any way to make this nut-free? Would really like to try this recipe.

    1. Martina @ KetoDietAuthor

      You can indeed! You could use flax meal (about 3 tbsp) or coconut flour (about 2 tbsp, plus a dash of water). I'll share a separate recipe for the quick bread soon.

      1. Susan

        That is great news! Thank you so much for your quick reply!

    This recipe looks like even I could do it, but will need to replace the egg by a "vegan egg": ground flax or chia seed plus 1-3 volumes of water (recipes vary, the idea is to replace the moisture in the egg with water). This should give the binding effect offered by the egg.
    And since flax seed is listed as a partial substitute for the almond flour - it should taste fine! Ground flax seed, chia seed, or even psyllium (yes, as in Metamucil capsules) are part of many vegan flatbread recipes as the binder. So it should work in this one.

    “bake 350 °F for 12-15 minutes” for what dimension of the container?

    1. Martina @ KetoDietAuthor

      About the same as the bread container, just ovenproof. It should be about the size of a regular slice of bread. A ramekin (1 to 1.5 cups) is another option - to create a "mug muffin".

  7. Amy

    This was a great alternative to other keto bread recipes I've found, which were reminiscent of sawdust but without the flavor. This was a little too dry though, how can I give it more moisture and stay keto?

    1. Martina @ KetoDietAuthor

      Thank you Amy! You could add moisture by adding one more tablespoon of olive oil or melted butter/ghee. Or you could add a tablespoon of cream cheese (if you can do dairy).

    90 second bread has become my fav! I make it in the oven and add faux apple pie filling on top to get a apple fritter/breakfast treat. I tried using protein powder instead of almond, doesn't work....stick to the recipe. I have sprinkled with almonds instead of faux apple pie but I like the apple pie.

    1. Martina @ KetoDietAuthor

      Thank you for sharing this Sher! I wonder about the faux apple pie topping, did you use zucchini? 😊

    What size of ramekin?

    1. Martina @ KetoDietAuthor

      These are made in shallow sandwich containers, about the size of a loaf but you could use a large ramekin too, I think that 1-cup ramekin will work just fine.

  10. Sharon

    Where did you find the square bread storage container? What is it made of?

    1. Martina @ KetoDietAuthor

      Hi Sharon, something like this will work: Amazon link
      Or you can even use a square glass container like this one: Amazon link

  11. sher

    Made it. Quick and easy. I made it in the oven just because I wanted that browning effect. Next time I will try microwave. I really crave that yeasty flavor. Do you know of anything that could be added to get that flavor?

    1. Martina @ KetoDietAuthor

      Hi Sher, I am actually working on a keto yeast bread recipe so you should see it on the blog in the next few weeks 😊
