01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss cauliflower florets with 2 tablespoons olive oil, smoked paprika, 1/2 teaspoon sea salt, and 1/4 teaspoon black pepper until evenly coated. Spread in a single layer on the prepared baking sheet.
03 - Roast for 25–30 minutes, tossing halfway through, until the florets are golden and fork-tender.
04 - While the cauliflower roasts, rinse the brown rice under cold water. In a medium saucepan, heat 1 tablespoon olive oil over medium heat. Add minced garlic and sauté for 1 minute until fragrant. Add the rinsed rice and stir to coat each grain in the oil and garlic.
05 - Pour in the vegetable broth and bring to a boil. Cover with a tight-fitting lid, reduce heat to low, and simmer for 35–40 minutes until the rice is tender and the liquid is fully absorbed.
06 - Remove the saucepan from heat and let stand, covered, for 5 minutes. Uncover and fluff the rice with a fork.
07 - Stir the lemon zest, lemon juice, chopped parsley, and dill (if using) into the rice. Season with salt and pepper to taste.
08 - Spoon the herbed brown rice onto plates, top with the roasted cauliflower, and garnish with extra parsley and lemon wedges.
