The Easiest Portobello Mushroom Mini Keto Pizza

No matter how long you’ve been on a keto diet, the occasional craving will still turn up for some of your old comfort foods, for me these mini mushroom keto pizzas help fight off one of my biggest carb filled weaknesses.

Pizza is definitely one of my most missed foods on the keto diet, not that it’s something I used to make myself!  Ordering a pizza was so convenient and tasty, but also one of the least healthy options I could make. Pizza for me was a pick me up, something I would get on the days I was feeling lazy, or had had a long day at work and just wanted something delicious, fast.

There are plenty of keto recipes out there to recreate the pizza dough base and get as close to the real thing as possible. But for me it’s the flavors and that convenience that I crave most. These portobello mushroom mini keto pizzas are great to get that fix, with minimal effort on my part.

The great thing here is how simple these are to make, needing virtually no cooking experience and very little time in the kitchen. I can put these together in a couple of minutes of actual work, and then go off and do something else until they’re ready. All the flavors of keto pizza without all the work that comes with trying to replicate the pizza dough base.

In terms of toppings I’ve gone for the classic pepperoni pizza here, keeping the ingredient list very short, which is great for doing keto on a budget too. You can go mad of course with whatever toppings you like! I’m thinking of doing a blue cheese and sage pizza next…

For me, one of the most important ways to keep people on the keto diet and not fall off the wagon is to make eating keto as simple and easy as possible. That means keeping the ingredients list for meals short and avoiding complex cooking methods where you can.

If you’re new to the keto diet, don’t jump in trying to make difficult dishes when you can build a repertoire of 3-4 quick and easy meals like this one instead. Once eating keto becomes second nature and you know you can quickly rustle up a low carb meal then move on to the harder stuff. I’ve listed out 10 really simple 15 minute keto dinners that I think make a great start for anyone beginning a keto diet.

The steps to make this one couldn’t be simpler! As an optional first step, pre-cook the mushroom to get the majority of their moisture out before adding toppings, and drain the pan and the mushrooms. Portobello mushrooms hold a lot of water which we want to get out. If you’re in a rush you can skip this step and just drain the pan at the end but personally I think it’s worth it, this adds maybe an extra minute to your total time working in the kitchen (plus 20 mins of cooking…)

Once you’re ready to add toppings you’ll first need marinara sauce (or any other low carb sauce that goes well with your chosen toppings). It’s important to check labels here as so many products contain lots of extra sugars and ingredients. If possible look for a specifically low carb product to really keep the carb count down. Alternative toppings like low carb alfredo sauce are great, and sometimes if I don’t have any sauce I’ll just make the whole think extra cheesy!

For the cheese and other toppings, feel free to go wild! Here I’m using sliced pepperoni, although chorizo is another favorite that’s very similar. Mozzarella is the classic cheese topping, I’m using fresh mozzarella here but the grated stuff works fine too. To be honest, I often just use whatever’s in my refrigerator, cheddar, blue cheese, feta. These are great for using up bits of leftover ingredients so do experiment.

Once you’ve piled your toppings on top, you can store the prepped mushroom keto pizzas in the refrigerator for later if you’re not planning to eat them right away. This is a great idea to have something easy at hand for those times when you can’t be bothered with cooking (my biggest trigger for eating non-keto foods and take aways!)
