Vegan Olive, Lentil & Mushroom Burger Recipe

Homemade vegan burgers

These olive, lentil, and mushroom burgers are a delicious vegan alternative without compromise. Not eating meat doesn’t mean you have to miss out on great food and great flavours, and these meat-free patties are a perfect example.

The olives are very prominent in these burgers, so they are particularly suitable for olive lovers. If you’re not sure about or dislike olives, you can give them a miss and still enjoy the recipe with tasty lentils and juicy mushrooms.

If you’re looking for inspiration on the perfect ingredients for your vegan burger, we recommend some good-quality vegan cheese, crispy fresh lettuce, juicy buffalo tomatoes, and tangy gherkins. But for an incredible, Mediterranean taste, why not pair your vegan patties with some lettuce, vegan pesto, and organic grilled peppers? At Real Italiano, our locally sourced products are packed with authentic flavours to enhance your home-cooked dishes, and these two ingredients will help add unique seasoning and spices to boost your vegan burgers.

A little bit about olives


Traditionally grown in the Mediterranean, olives come in a range of green and black shades. Like most fruits and vegetables, the colour of olives refers to how ripe they are – green olives and unripe and black olives are fully ripe.

Normally, once picked, olives are either pressed and made into olive oil or marinated and preserved in jars.

Olives are an incredibly versatile ingredient – they can be eaten whole with the stone removed or used in many ways in cooking. In Italy, olives are an important part of food culture. They are most often served as a snack or starter, or in pasta dishes and sauces. One of the most famous pasta recipes that contain olives is Pasta Puttanesca, which is a simple tomato-based pasta dish containing olives and capers.

Fun fact: olives are a fruit, not a vegetable!

In terms of nutritional benefits, olives have quite a lot to offer, but watch out as they can be high in salt, especially those preserved in brine. However, they are high in antioxidants and are a source of potassium and calcium. Also, as a popular fermented food, olives contain some helpful digestive bacteria, which can support gut health.   

Organic Mediterranean Olives

To keep the recipe nice and simple, we’ve used the Bio Gustiamo Organic Mixed Pitted Olives, which consist of green and black olives. They are seasoned with aromatic spices and preserved in oil, which adds incredible flavour to this recipe.

However, if you prefer certain olives over others, we have a selection of green and black olives in either oil or brine preserves. If you’re looking for something a little more adventurous, why not try the Spiced Green Olives, which are seasoned with cumin and chilli for some added heat, or if you really love olives, you could give the Whole Black Olives a try, which is the “Peranazana” type with a more intense flavour.

Vegan Olive, Lentil & Mushroom Burger Recipe


2 tbsp Casa Rinaldi Extra Virgin Olive Oil with Truffle

1 onion, diced

220g brown button mushrooms, sliced

3 tsp Familia Suarez Diced Garlic

Black pepper


½ tsp dried thyme

½ tsp dried tarragon

100g Bio Gustiamo Organic Mixed Pitted Olives in Oil

35g tinned lentils, drained

200g breadcrumbs

2 tbsp soy sauce


Cooking method

1. Preheat the oven to 200°C/180°C fan/gas 6. To a large non-stick frying pan, add the olive oil and, once hot, add the diced onion. Fry for a few minutes and season with a pinch of salt.

2. Once the onions are fragrant and start to gain some colour, add the sliced mushrooms, garlic, thyme, and tarragon, and continue to fry for another 7-10 minutes until the mushrooms are cooked.

3. Meanwhile, place the olives in a food processor or chopper and pulse until they are finely chopped up. Remove the chopped olives and set them aside.

Top tip: be sure not to over-pulse the olives to avoid them turning into a purée.

4. Once the mushrooms are cooked, add the mushroom and onion mixture to a food processor or chopper. Then, add all other ingredients apart from half of the breadcrumbs. Pulse the ingredients until mostly smooth but with some texture, then transfer to a mixing bowl.

5. Add the remaining half of the breadcrumbs to the bowl, followed by the chopped olives, and combine.

6. Line a baking sheet with baking paper. Then, divide the burger mix into 6 equal portions.

Top tip: An easy way to split the burger mixture is to divide it in half and divide the halves into 3 pieces each.

7. Form the burger mix portions into round patties and place them on the baking sheet. Place the burgers in the hot oven and bake for 12-15 minutes until browned.

Top tip: If you want nice and neat burger patties, an easy way to do this is to shape them using round cookie cutters. This will make your burgers round, even, and smooth around the edges. Alternatively, for more rustic burgers, do it free-handed!

As the days get warmer, why not give these vegan burgers a go on the barbecue? The fire will give your patties a delicious smoky flavour! Just before you take them off the grill, throw some brioche buns on to toast for a couple of minutes and enjoy!
