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 brown and fork-tender.
04 - While the cauliflower roasts, rinse the brown rice under cold water. Heat 1 tablespoon olive oil in a medium saucepan over medium heat. Add minced garlic and sauté for 1 minute until fragrant. Stir in the rinsed rice to coat evenly in the oil and garlic.
05 - Pour in the vegetable broth, bring to a boil, then cover and reduce heat to low. Simmer for 35–40 minutes until the rice is tender and all liquid is absorbed.
06 - Remove from heat and let stand, covered, for 5 minutes. Fluff gently with a fork.
07 - Stir in the lemon zest, lemon juice, chopped parsley, dill (if using), and salt and pepper to taste. Mix until evenly distributed.
08 - Spoon the herbed brown rice onto plates, top with the roasted cauliflower, and garnish with extra parsley and lemon wedges. Serve immediately.
