Ingredients
- 4 large yellow onions, peeled and quartered
- ½ cup unsalted butter (1 stick), cut into pieces
- 4 cloves garlic, minced
- 1 tablespoon Italian seasoning
- ½ teaspoon salt
- ½ teaspoon black pepper
- ¼ teaspoon red pepper flakes (optional)
- ¼ cup grated Parmesan cheese (optional)
- Fresh parsley, chopped (for garnish)
Instructions
1. Prepare the Onions
Peel the onions and cut them into quarters. Separate the layers slightly so the butter and seasoning can coat them evenly.
2. Season
Place the onions in a large pot or deep skillet.
Add the butter pieces, minced garlic, Italian seasoning, salt, black pepper, and red pepper flakes.
3. Cook
Cover and cook over medium-low heat for about 25–30 minutes, stirring occasionally.
The onions will soften and become tender while absorbing the garlic butter and seasoning.
If needed, reduce heat to prevent browning — this is more of a gentle simmer than a sauté.
4. Finish
Once tender, remove from heat.
Sprinkle with grated Parmesan cheese if desired and garnish with fresh parsley.
Serve warm.
Optional Foil Packet Method
For grilling:
- Place seasoned onions and butter in a large foil packet.
- Seal tightly.
- Grill over medium heat for 25–30 minutes, turning once halfway through.
- Carefully open and serve.
Serving Suggestions
- Alongside grilled steak or chicken
- With roasted potatoes
- As a topping for burgers or sandwiches
- Mixed into pasta
- Served with crusty Italian bread
