When you get hungry, it's more likely to be tempted and have an unhealthy snack. Being able to quickly make a low-carb snack like this one will help you stick with the ketogenic diet. I love the convenience of mug muffins. Just like most of you, I don't always have time to cook - mug muffins, avocados, hard boiled eggs are my go-to keto meals. If you don't have a microwave, I included some tips for baking the muffins in the oven :-)

Tips & Substitutions

Cooking in the oven: If you don't have a microwave, I suggest you make 4-8 servings at once. Preheat the oven to 175 °C/ 350 °F (fan assisted), or 195 °C/ 380 °F (conventional) and cook for about 15 minutes or until cooked in the centre.

Crisping up the bacon: Preheat the oven to 190 °C/ 375 °F. Line a baking tray with baking paper. Lay the bacon strips out flat on the baking paper, leaving space so they don't overlap. Place the tray in the oven and cook for about 10-15 minutes until golden brown. The time depends on the thickness of the bacon slices. When done, remove from the oven and set aside to cool down.

Cooking the spinach: Fill a sauce pan with water and bring to a boil over a high heat. Once simmering, add the spinach and cook for just about a minute until wilted. Transfer the leaves into a bowl with cold water. Then, strain and squeeze the water out of the leaves. If you're using frozen and thawed spinach, make sure you squeeze any water out.

If you need to make this recipe nut-free, use more flaxmeal (same amount) or coconut flour (half the amount). When using ingredients, always go by their weight, especially in case of baked goods. Measures such as cups may vary depending on the brand.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

All of your recipes look and some even taste wonderful, new to Keto but so far so good. I was wondering on the bacon, egg & cheese mug muffin can I replace the feta with Goat cheese?  There is something about feta that just doesn’t work for me.  I am hoping that goat cheese is a safe substitute?
Thank You so Much !!!!

Hello Brooke, you can definitely make that swap. Goat's cheese works really well as a replacement for feta!

Thank You so Much for getting back to me so quickly.

Do these freeze and reheat well?

Yes they do! The only issue might be the cheese because some types contain more moisture. It's best if you can reheat these in the oven to remove some of it.

More of a question vs comment: can you pre-make these and heat and eat? Do they keep well in the fridge?
Kind regards,

Hi Kathleen, I think you can but they may get a little dry when you reheat them. I would store them in an airtight container in the fridge to minimise that.

Just wanted to say thanks for all the recipes! I've been researching and reading up on Keto the past few days and I'm about to start it tomorrow. Just a few questions:
You say the zucchini/eggplant/mushroom ect chips are very occasional snacks. How often? I get that there's a set carb limit for best results and so it all works, I just ask because I'm already on a low-sulphur diet which is very limiting and therefore I'm not allowed eggs, onion, garlic and getting sick of meat, plus more. Out of the listed snacks/extras on your 7 day keto plan, which would you say would be the best? I just ask because I might be needing to snack more? I don't even know if that'll be possible to stay within carb intake. Any info would be appreciated!

Hi Rebecca, thank you!. I think that low-carb chips & crisps won't be the best option, at least not for this purpose. You can have them as long as you don't hoover your carb limit but there are other foods that are much better for appetite control. How about avocados or a handful of macadamia nuts? Both are very low in carbs and will help yeasty fuller for longer. Hope this helps!
