Instructions
Cooking red lentils
Rinse the red lentils, place them in a saucepan with cold water, bring to a boil and cook for 20 minutes until very tender but still slightly firm. Drain and set aside.
Time: PT20M
Cooking sweet potatoes
Preheat the oven to 190°C. Peel 300 g of sweet potatoes, cut into large dice and spread on a baking sheet lined with parchment paper. Bake for 45 minutes until tender. Let cool, then mash with a fork leaving some chunks for texture.
Time: PT45M
Temperature: 190°C
Sauté aromatics
In a pan, heat 2 tbsp olive oil over medium heat. Add the 2 finely chopped shallots, the crushed garlic clove and the spring onions in rounds. Sauté for 5 minutes until translucent.
Time: PT5M
Mix the bases
In the bowl, combine the cooked lentils, the sweet‑potato purée, the shallot/garlic/onion mixture, smoked paprika, cumin, Herbes de Provence and thyme. Salt and pepper to taste. Mix by hand until a homogeneous but still slightly grainy consistency is reached.
Time: PT5M
Add the binder
Add the cornstarch, breadcrumbs and beaten egg (or flax‑water mixture). Mix quickly until everything holds together when forming a ball.
Time: PT3M
Shape the steaks
Divide the mixture into 4 equal parts. With hands, form patties about 1.5 cm thick. Use a cookie cutter or the edge of a knife to flatten slightly and obtain a uniform shape.
Time: PT5M
Bake
Place the patties on the same baking sheet, slightly spaced. Bake at 180°C for 20 minutes, turning halfway through to achieve a nice coloration on both sides.
Time: PT20M
Temperature: 180°C
Pan option for finishing
If you prefer a crispier surface, heat 1 tbsp olive oil in a pan over medium‑high heat and sear each steak 2‑3 minutes per side after the oven step.
Time: PT6M

Critical Steps — Do Not Skip

Chef Tips from the Video
- Sprinkle a pinch of brown sugar with the paprika to accentuate the caramelization of the sweet potatoes.
- Serve with a Greek yogurt, lemon and chives sauce for a fresh contrast.
- Add a few arugula leaves to the burger for peppery bite and crunch.
Troubleshooting
Steaks fall apart during cooking
Add an extra 1‑2 tbsp of breadcrumbs or cornstarch to strengthen the binder.
Texture too dry
Incorporate 1‑2 tbsp of water or vegetable broth into the mixture before shaping.
Surface not browned enough
Increase the oven temperature to 200°C for the last 5 minutes or quickly sear in a pan.
Storage

Make-Ahead Tips
- Prepare the lentil and sweet‑potato mixture the day before and keep refrigerated; shape the steaks on the day of cooking.
