Spicy Keto Tuna Melt Muffins with Celery

Pinterest Hidden Image

Keto tuna melt is one of my all-time favourite keto snacks. I love to make egg cups as an after-school snack for my little one to eat when she gets in and when I stumbled upon this recipe on Pinterest, I had to give it a try.

Before going keto, tuna sandwiches were one of my favourite things to eat. I’d have two sandwiches every morning for breakfast maybe 4 or five times a week. Whew, no wonder I was struggling to maintain my weight eating all that bread!

I was so happy to find this tuna melt recipe that incorporated one of my favourite snack. This is one of the things I love about keto, all the yummy foods that’s allowed on this way of eating. This helps to make it more of a long-term lifestyle and less of a restrictive diet for me.

Keto Tuna Melt Muffins

If you’re struggling to get your children or family in general to eat more vegetables, or heck, if you’re struggling to get more veggies into your diet, egg cups are a great way to do this.

They’re truly so versatile that all you need to do is whip up some eggs and heavy whipping cream with your favourite meat and veggies and loads of cheese. I use celery in this recipe because it lends itself really well to the tuna and spices. I imagine it would also work well with kale or mustard greens.

No muffin pan or cups? No problem, bake it in a glass dish to make an egg bake, something I show off here before I got my silicone cups.

The best thing about egg cups is that they freeze well which means they’re great as a keto meal prep breakfast, lunch or snack. With all the delicious varieties of egg cups you could make, it’s a great way to wean kids off unhealthy snacks and start transitioning them to a healthier low carb lifestyle. Here’s how I approach the keto diet with my kid.

If you’re lost and unsure how to start the keto diet, this meal plan is for you. It’s a foolproof guide to winning at the high-fat, low-carb lifestyle. Enter your details below and start now!

How to Make Tuna Melt Cups


Now, if you’re really feeling for the traditional tuna melt, you could simply swap out the bread for the keto version. I do this sometimes to satisfy my bread cravings.

I use my favourite coconut flour egg loaf recipe as the base, layer it with tuna, tomatoes and cheese and pop that bad boy in the toaster oven open faced for a delicious keto meal.

But let’s get into this almost zero carb version. The best cheese for a tuna melt cup is gonna be your standard sharp cheddar cheese but feel free to use your favourite variety.

With 11g of protein and 1.5 net grams of carbs total, this recipe is a winner for me.
