Preparation steps

  1. Start by making the miso butter. Mix all ingredients in a small bowl and set aside.
  2. Light the grill and wait until the coals are ash colored.
  3. Once the coals are ready, place more coals on one side to create two heating zones.
  4. Brush the mushrooms and onions with a little miso butter.
  5. Place the mushrooms and onions on the grill and cook for 10 minutes. Be sure to baste and turn occasionally.
  6. Use a spatula to turn the onions over so they don’t separate into rings.
  7. Once the vegetables are charred and tender, move them to the cooler side of the grill to keep them warm.
  8. Continue to drizzle the miso butter over the vegetables from time to time.
  9. Cook the halloumi directly on the grill until browned and slightly charred.
  10. While the halloumi is cooking, brush the cut sides of the rolls with the remaining miso butter and toast them on the grill.
  11. Finally, assemble the burgers by filling the buns with the cooked mushrooms, onions, halloumi, tomatoes, rocket and burger sauce.

Health Benefits of Miso Mushroom and Halloumi Burgers

The miso mushroom and halloumi burgers not only provide a delicious and flavorful meal but also provide several health benefits. Let’s take a closer look at the key ingredients and how they contribute to your well-being:

1. Portobello mushrooms

Portobello mushrooms are the star of these burgers and provide numerous health benefits. These large mushrooms are rich in essential nutrients such as fiber, vitamins (especially B vitamins), and minerals (including potassium and selenium). They are also an excellent source of antioxidants, which protect your cells from free radical damage.

2. Halloumi

Halloumi, a semi-hard cheese made from sheep’s and goat’s milk, gives the burgers a deliciously salty and chewy texture. Although it is a high-fat cheese, halloumi is also a good source of protein and essential minerals such as calcium and phosphorus, which are crucial for maintaining healthy bones and teeth.

3. Arugula (pepper leaves)

Adding arugula or other peppery leaves to these burgers not only adds a satisfying crunch but also increases their nutritional value. Arugula is a nutrient-rich leafy vegetable that contains vitamins A, C and K as well as folic acid and iron. It is also known for its potential antioxidant and anti-inflammatory properties.

4. Miso sauce

The miso sauce used to marinate the mushrooms and halloumi is not only delicious but also offers health benefits. Miso is a traditional Japanese seasoning made from fermented soybeans and is therefore rich in beneficial probiotics that support gut health. It is also a good source of plant-based protein and contains important minerals such as manganese, copper and zinc.

5. Tomatoes

Sliced ​​tomatoes are a classic accompaniment to burgers and not only provide a kick of freshness, but also important nutrients. Tomatoes are rich in vitamins A, C, and E, as well as antioxidants like lycopene, which may help reduce the risk of certain chronic diseases.

By combining these nutritious ingredients, miso mushroom and halloumi burgers offer a guilt-free alternative to traditional meat burgers, delighting your taste buds and providing numerous health benefits.
