  Ingredients
• 1 medium green cabbage, cut into thick wedges
• 2 large yellow onions, sliced into thick wedges
• 3 tablespoons olive oil
• 3 cloves garlic, minced
• 1 teaspoon paprika
• 1 teaspoon garlic powder
• ½ teaspoon onion powder
• ½ teaspoon dried thyme
• ½ teaspoon black pepper
• ¾ teaspoon salt, or to taste
• 1 tablespoon fresh parsley, chopped
• 1 tablespoon lemon juice (optional)
• ¼ teaspoon red pepper flakes (optional)
  Instructions
  Step 1: Preheat the Oven
  Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper or lightly grease it with olive oil.
  Step 2: Prepare the Vegetables
  Remove any damaged outer leaves from the cabbage. Cut it into thick wedges, keeping a little of the core attached so the wedges hold together. Peel and slice the onions into thick wedges.
  Step 3: Make the Seasoning
  In a small bowl, combine the olive oil, minced garlic, paprika, garlic powder, onion powder, dried thyme, salt, and black pepper. Mix well.
  Step 4: Coat the Cabbage and Onions
  Place the cabbage wedges and onion wedges on the prepared baking sheet. Brush or drizzle the seasoning mixture over the vegetables, making sure to coat all sides evenly.
  Step 5: Roast the Vegetables
  Roast for 20 minutes. Carefully flip the cabbage wedges and turn the onions. Return the tray to the oven and roast for another 15–25 minutes, until the cabbage is tender and the edges are golden brown and slightly crispy.
  Cooking time may vary depending on the thickness of the cabbage wedges.
  Step 6: Add the Finishing Touches
  Remove the vegetables from the oven. Sprinkle with fresh parsley and drizzle with lemon juice if desired. Taste and adjust the seasoning.
  Step 7: Serve and Enjoy
  Serve hot as a flavorful side dish alongside roasted chicken, grilled fish, steak, or your favorite vegetarian meal.
  Tips for the Best Roasted Cabbage and Onions
• Cut evenly: Similar-sized wedges help the vegetables cook evenly.
• Avoid overcrowding: Spread the vegetables out so they roast rather than steam.
• Get crispy edges: Roast at a high temperature and turn the cabbage halfway through.
• Add extra flavor: Sprinkle with Parmesan cheese during the last 5 minutes of roasting.
• Make it spicy: Add red pepper flakes or a pinch of cayenne pepper.
• For extra sweetness: Use sweet onions or drizzle with a little balsamic vinegar before serving.

  Recipe Q&A
  Q1: Can I make roasted cabbage and onions ahead of time?
  Yes. Roast the vegetables ahead of time and refrigerate them in an airtight container. Reheat in the oven to help restore their crispy edges.
  Q2: How do I store leftovers?
  Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
  Q3: Can I freeze roasted cabbage and onions?
  Yes, but the texture may become softer after thawing. Freeze in a suitable airtight container for up to 2 months for best quality.
  Q4: How do I make the cabbage extra crispy?
  Dry the cabbage thoroughly before seasoning, avoid overcrowding the baking sheet, and roast at 425°F (220°C).
  Q5: Can I use red cabbage instead of green cabbage?
  Yes. Red cabbage works well, although its flavor is slightly stronger and its color may deepen during roasting.

  No nuts are included in the recipe as written. Check ingredient labels and avoid cross-contact if preparing food for someone with a nut allergy.
