How to Make Creamy Oven Baked Onions :
Follow these simple steps to prepare this delicious and comforting side dish:
“Soft, tender onions meet a velvety cream sauce for a dish that’s as easy to make as it is impressive to serve.”
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a baking dish with 1 teaspoon butter, ensuring it’s evenly coated.
Step 2: Prepare and Simmer the Onions
Peel the onions and trim the tops and tails using a sharp knife. In a large saucepan, add 6 cups of water and ½ teaspoon sea salt. Bring the water to a boil, then add the onions.
Reduce the heat to a simmer and cook the onions for 20 minutes, or until they are tender when pierced with a fork.
“Simmering the onions beforehand ensures they’re perfectly tender and absorb the creamy sauce during baking.”
Step 3: Arrange in the Baking Dish
Drain the onions and let them cool slightly. Cut each onion in half and arrange them flat-side down or cut-side down in the prepared baking dish.
Tuck the thyme sprigs between the onion halves to infuse the dish with herbal flavor.
Step 4: Add the Cream and Seasoning
Pour 1½ cups heavy whipping cream evenly over the onions. Sprinkle with ¼ teaspoon freshly ground pepper for a hint of spice.
Step 5: Bake Until Golden
Place the dish in the preheated oven and bake, uncovered, for 20-25 minutes, or until the cream is bubbling and the top is lightly golden brown.
“The bubbling cream and golden edges create a luxurious finish that’s as tasty as it looks.”
Step 6: Garnish and Serve
Remove the thyme sprigs and garnish the dish with 2 tablespoons freshly chopped parsley. Serve the onions warm, directly from the baking dish.
Tips for the Best Creamy Oven Baked Onions :
“For perfectly tender and flavorful onions, follow these expert tips!”

- Don’t Skip the Simmering Step: Boiling the onions first ensures they cook evenly and become perfectly tender.

Customization Ideas :
- Cheesy Variation: Sprinkle grated Parmesan or Gruyère over the top before baking for a cheesy twist.
- Add Garlic: Place a few whole garlic cloves in the dish for extra flavor.
- Use Shallots: For a more delicate flavor, substitute small onions with whole shallots.
