Ingredients
- 4 large onions
- ½ cup butter, melted
- 1 tablespoon olive oil
- 1 cup beef broth
- 1 teaspoon minced garlic
- 1 teaspoon parsley flakes
- 1 teaspoon brown sugar
- 1 teaspoon Cajun seasoning
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika
- ½ teaspoon cracked black pepper
Step-by-Step Instructions
Step 1: Prep Your Onions for Maximum Flavor
- Preheat your oven to 350°F (175°C).
- Peel your onions and cut them in half.
- Make crosswise cuts into each onion half to allow the butter and seasoning to soak into every layer.
Step 2: Make the Buttery Cajun Sauce
- In a bowl, whisk together the melted butter, olive oil, and all the spices: Cajun seasoning, smoked paprika, garlic powder, black pepper, minced garlic, parsley flakes, and brown sugar.
- Stir until fully blended and fragrant.
Step 3: Assemble and Bake
- Place the onion halves, cut-side up, in a baking dish.
- Drizzle the seasoned butter mixture over each onion to coat them well.
- Pour the beef broth into the bottom of the dish for steam and moisture.
- Cover tightly with foil to trap all that flavor while it bakes.
Step 4: Bake to Perfection
- Bake for 45–60 minutes or until the onions are soft, golden, and rich with buttery flavor.
- For extra caramelization, remove the foil during the last 10 minutes of baking.
Pro Tips & Serving Suggestions
- Spice it Up: Add extra Cajun seasoning or hot sauce if you like a bolder kick.
- Pair It Up: These onions are amazing with baked salmon, grilled steak, roasted chicken, or a bowl of buttery mashed potatoes.
- Add Cheese: Sprinkle shredded parmesan or mozzarella during the last 5–10 minutes for an indulgent, melty topping.
