Ingredients

For the Lentil Base:

• 1 cup dry green or brown lentils, rinsed (do not use red or yellow lentils, as they will turn mushy)

• 2 cups vegetable broth (or water)

• 1 tbsp extra virgin olive oil

• 1/2 small yellow onion, finely diced

• 1/2 tsp dried oregano

• 1/4 tsp smoked paprika

• Salt and black pepper to taste

For the Tomato & Caper Relish:

• 1.5 cups cherry tomatoes, halved

• 3 tbsp capers, drained and lightly chopped

• 3 cloves garlic, minced

• 1 tbsp fresh lemon juice

• 1.5 tbsp fresh parsley, chopped

• 1.5 tbsp extra virgin olive oil

• 1/2 tsp dried oregano

• Pinch of red pepper flakes (optional)

Instructions

1. Cook the Lentils: In a medium saucepan, combine the olive oil and finely diced onion. Sauté over medium heat until the onion is soft and translucent (about 5 minutes). Add the rinsed lentils, vegetable broth, dried oregano, and smoked paprika. Bring to a boil, then reduce the heat to low, cover, and simmer for 25–35 minutes, or until the lentils are tender but still have texture. (Add more liquid if needed). Drain any remaining liquid. Season with salt and pepper to taste.

2. Preheat Oven: While the lentils cook, preheat your oven to 200°C (400°F). Lightly grease a baking dish or a small casserole dish with olive oil.

3. Mix the Relish: In a small bowl, toss together the cherry tomatoes, capers, garlic, lemon juice, parsley, and the larger portion of extra virgin olive oil. Add the red pepper flakes and season with a pinch of salt and pepper.

4. Top and Bake: Spread the cooked lentils in an even layer in the prepared baking dish. Spoon the tomato and caper relish generously over the top of the lentils.

5. Cook: Bake for 20–25 minutes, or until the tomato relish is bubbly, the tomatoes are soft and beginning to burst, and the edges are lightly caramelized.

6. Serve: Garnish with extra fresh parsley and a squeeze of fresh lemon juice.

Tips & Variations: Make-Ahead & Storage

• Make-Ahead: You can prep the cooked lentils and the tomato relish up to 2 days in advance and store them separately in the fridge. To serve, gently reheat the lentils and then top with the relish and bake as instructed.

• Storage: This baked vegetarian dish is excellent the next day. Store leftovers in an airtight container for up to 3 days. Reheat gently in the oven or microwave.

• Variations: Swap the green lentils for French Puy lentils for a slightly peppery flavor. You can also stir a handful of fresh spinach into the warm lentils before baking for added greens.

FAQ

Is this recipe completely vegan? Yes, this is a fully plant-based recipe. Just ensure that your vegetable broth is vegan-certified if needed.

Can I use canned lentils? Yes, you can use canned lentils! Drain and rinse 2 (15-oz) cans of cooked lentils and skip step 1. You may still want to sauté the onion and garlic and toss them with the canned lentils before baking for the best flavor.

Do I have to use cherry tomatoes? Nope. Diced plum tomatoes, Roma tomatoes, or even good-quality canned diced tomatoes (drained) will work well.
