Instructions

1. Step 1: Preheat oven to 400°F. Toss 2 medium peeled and diced beets with 1 tbsp olive oil, 1/4 tsp salt, and 1/4 tsp black pepper on a baking sheet. Roast for 25 minutes until tender and caramelized.
2. Step 2: In a large pot, heat 1 tbsp olive oil over medium heat. Add 1 medium diced onion, 1 medium diced carrot, and 2 diced celery stalks, and cook for 5 minutes until softened. Add 2 minced garlic cloves and cook for 1 minute until fragrant.
3. Step 3: Stir in 1/2 cup rinsed green lentils, 4 cups chicken broth, 1/2 tsp dried thyme, 1/2 tsp salt, and 1/4 tsp black pepper. Bring to a boil, then reduce heat and simmer for 20 minutes until lentils are tender.

Meanwhile, in a small skillet, heat 1 tbsp oil over medium heat and fry the 2 thinly sliced shallots until golden and crispy, about 3-4 minutes. Drain on paper towels.
