For the Filling
- 2 large red onions (thinly sliced) – Sweet and savory, they are the star ingredient in this red onion recipe.
- 2 tablespoons olive oil – Used for sautéing, it adds richness and depth to the caramelized onions.
- 1 teaspoon balsamic vinegar – This gives a subtle tang that complements the sweetness of the onions beautifully.
- 1 cup goat cheese (crumbled) – Creamy and tangy, goat cheese adds a wonderful contrast to the savory filling.
- 2 large eggs – These act as a binding agent, helping everything hold together perfectly in your tart.
- ½ cup heavy cream – Adds a luxurious richness that makes each bite indulgent and satisfying.

Step-by-Step red onion recipes
1. Mix the Dough: In a bowl, mix 1 cup all-purpose flour and ¼ teaspoon salt. Cut in ½ cup cold, cubed unsalted butter until the mixture resembles coarse crumbs. Stir in 3 tablespoons ice water until a dough forms. Wrap in plastic and refrigerate for 30 minutes.
2. Caramelize the Onions: In a skillet, heat 2 tablespoons olive oil over medium heat. Add 2 large thinly sliced red onions and cook, stirring occasionally, for about 20 minutes until they are soft and beautifully caramelized. Stir in 1 teaspoon balsamic vinegar and remove from heat.
3. Prepare the Crust: Preheat your oven to 375°F (190°C). Roll out the chilled dough on a lightly floured surface and fit it into a pie dish, ensuring even coverage along the edges.
4. Spread the Onions: Evenly spread the caramelized onions over the crust, letting their sweet aroma fill your kitchen as you do so.
5. Combine Filling Ingredients: In a bowl, whisk together 2 large eggs, ½ cup heavy cream, 1 teaspoon fresh chopped thyme, and 1 teaspoon freshly ground black pepper. Pour this creamy mixture over the caramelized onions before topping with 1 cup crumbled goat cheese.
6. Bake to Perfection: Bake in your preheated oven for 25-30 minutes until the tart is set and golden brown on top. Allow it to cool slightly before slicing into delicious wedges.
Optional: Garnish with fresh thyme leaves for an extra touch of flavor.

Expert Tips
- Butter Temperature: Use cold butter to create a flaky tart crust; room temperature butter will make it dense.
- Onion Caramelization: Stir frequently while caramelizing red onions to prevent sticking and ensure even cooking for that sweet flavor.
- Dough Consistency: Avoid overworking the dough; stop mixing as soon as it comes together to maintain a tender crust.
- Egg Mixture: Whisk eggs and cream thoroughly to avoid clumps in your filling, ensuring a smooth texture that complements the red onion recipes.
- Baking Time: Keep an eye on your tart towards the end of baking; every oven is different, and you want it golden but not burnt.
How to Store and Freeze red onion recipes
- Fridge: Store the tart in an airtight container for up to 3 days. This preserves the flavors of the caramelized red onions and goat cheese beautifully.
- Freezer: Wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag for up to 2 months. Perfect for quick appetizers!
- Reheating: Thaw overnight in the fridge, then reheat in a preheated oven at 350°F (175°C) for about 15-20 minutes. This restores the delightful texture of your red onion recipes.
- Ingredient Storage: Keep any leftover goat cheese and heavy cream sealed tightly in their original containers in the fridge for optimal freshness, using them within a week.

red onion recipes Questions Answered
What type of flour is best for the tart crust?
All-purpose flour works wonderfully for this tart crust, providing the right balance of structure and tenderness. If you're looking for a gluten-free option, consider using a 1: 1 gluten-free baking flour blend instead!
How do I know when the onions are properly caramelized?
Caramelizing red onions takes about 20 minutes over medium heat. You’ll know they’re ready when they are soft, deeply golden, and have a rich, sweet aroma. Stir them occasionally to prevent burning and encourage even cooking.
Can I make the tart crust in advance?
Absolutely! You can prepare the tart crust up to 2 days ahead. After mixing and forming the dough, wrap it tightly in plastic wrap and store it in the refrigerator. Just remember to roll it out once it’s chilled before filling and baking.
What’s the best way to store leftovers?
If you have any leftover tart, let it cool completely before covering it with plastic wrap or aluminum foil. Store it in the refrigerator for up to 3 days. To reheat, simply pop it back into a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through.
Can I freeze the caramelized onions or the entire tart?
Yes! The caramelized onions can be frozen in an airtight container for up to 3 months.

When you’re ready to enjoy it, thaw overnight in the refrigerator before reheating.
What can I substitute for goat cheese if needed?
If goat cheese isn’t your favorite or you need a dairy-free option, try using feta cheese for a similar tangy flavor or a vegan cream cheese alternative for a non-dairy version. Both will provide a delicious twist to your savory tart!
