Ingredients for Microwave Cheese & Rosemary Popcorn

- ⅓ cup (60g/2oz) popcorn kernels
- 3 tablespoons (1½ oz/45g) butter, melted
- 4 tablespoons dried cheese (parmesan or cheddar)
- ¼ teaspoon mustard powder
- 1 tablespoon chopped rosemary (dried or fresh)
- ½ teaspoon salt
Step-by-Step Instructions
- Place the popcorn kernels in a medium brown paper bag. Roll the top tightly to seal, trapping the steam for cooking.
- Stand the bag upright in the microwave and cook for 1 minute 35-50 seconds, or until the popping slows to about 1 pop per second. (Note: Cooking time may vary based on microwave wattage. For a 1200-watt microwave, this timing works well.)
- Carefully open the bag and pour in the melted butter. Roll the bag closed again and shake vigorously to coat the popcorn evenly.
- In a small bowl, mix the dried cheese, mustard powder, chopped rosemary, and salt.
- Sprinkle the cheese mixture over the popcorn while shaking the bag to distribute the seasoning evenly. Roll the bag closed and shake vigorously one more time.
- Serve immediately and enjoy your flavorful, cheesy popcorn!
Flavor Twists & Topping Ideas
Want to mix things up? Try swapping the cheddar cheese powder for nutritional yeast for a vegan-friendly option. For a spicy kick, add a pinch of cayenne pepper or smoked paprika to the seasoning mix. If you’re feeling adventurous, drizzle a little truffle oil over the popcorn before shaking in the seasonings for a gourmet touch.
Perfect Pairings for Your Popcorn
This cheesy rosemary popcorn pairs wonderfully with a crisp white wine or a cold beer for a cozy snack. For a movie night, serve it alongside a bowl of roasted nuts or a charcuterie board. It’s also a great addition to a game-day spread with other finger foods like wings or sliders.
Quick Tips for Microwave Success
To avoid burnt popcorn, *listen closely*—stop the microwave when the popping slows to about 1 pop per second. If your microwave is less powerful than 1200 watts, add 10-15 seconds to the cooking time. Always use a fresh brown paper bag to prevent any unwanted flavors or burns.
Storage & Reheating Made Easy
If you have leftovers (unlikely!), store the popcorn in an airtight container at room temperature for up to 2 days. To revive its crispiness, reheat it in the microwave for 10-15 seconds. Avoid adding more butter or cheese powder until after reheating to keep it from getting soggy.
Why This Recipe Works
The brown paper bag method is a *game-changer*—it traps steam for perfectly popped kernels without the need for special equipment. The combination of melted butter and cheese powder ensures every bite is flavorful, while the rosemary adds a fresh, aromatic twist. It’s quick, easy, and totally customizable!
