French Onion Pizza Ingredients
For the Onion Mixture:
• Unsalted Butter – Adds richness and moisture to the onion mixture. Can use salted butter but reduce added salt.
• Olive Oil – Enhances flavor and helps in sautéing onions. Any neutral oil may work.
• Yellow Onions (6 medium) – Main ingredient, providing sweetness and depth of flavor when caramelized. Sweet onions or shallots can be used for a milder taste.
• Sugar (1/4 tsp) – Aids in the caramelization process of onions, enhancing their sweetness. Avoid omitting for desired flavor.
• Kosher Salt & Freshly Ground Black Pepper – Essential for seasoning the onion mixture. Adjust to taste.
• Crème Fraîche (1 Tbsp) – Adds creaminess and a slight tang to the onion topping. Sour cream can be used in a pinch.
For the Cheese Topping:
• Gruyère Cheese (6 oz, grated) – Provides a nutty flavor and melts beautifully, enhancing the pizza’s richness. Emmental cheese may be a close alternative.
• Parmesan Cheese (6 oz, grated) – Adds a sharpness and depth to the cheese blend. Pecorino Romano can work as a substitute.
For the Pizza Dough:
• All-Purpose Flour – The base for the pizza dough. Gluten-free flour can be used for a gluten-free option.
• Honey (1 Tbsp, pure lavender honey preferred) – Imparts a subtle sweetness to the dough. Regular honey or agave syrup is suitable.
• Fresh Thyme – Provides aromatic garnishing for the finished pizza. Dried thyme can be used, but will yield less flavor.

Step‑by‑Step Instructions for Savory French Onion Pizza
Step 1: Prepare Onion Mixture
In a large skillet over medium-low heat, melt 2 tablespoons of unsalted butter with 1 tablespoon of olive oil. Add 6 medium sliced yellow onions, cover, and sauté until tender, about 18-20 minutes. Once tender, uncover, increase heat to medium, stir in 1/4 teaspoon sugar and a pinch of kosher salt, and cook until the onions are golden brown and caramelized for 20-30 minutes. Let cool, then mix in 1 tablespoon of crème fraîche and 1 1/4 cups each of grated Gruyère and Parmesan cheese.
Step 2: Make the Dough
In a mixing bowl, combine 2 cups of all-purpose flour, 1 teaspoon of kosher salt, and 1 packet of yeast. Slowly add 3/4 cup of warm water and 1 tablespoon of honey, along with 1 tablespoon of olive oil, mixing until combined. Knead the dough on a floured surface for about 5 minutes until smooth. Let it rest for 15 minutes, allowing the gluten to relax for a better texture in your French onion pizza crust.
Step 3: Bake Pizza
Preheat your oven to 450°F (232°C). Roll out the rested dough on a floured surface into a rectangle that fits your greased baking sheet. Transfer the dough onto the sheet, then spread the cooled onion mixture evenly over the top. Sprinkle the remaining cheese over the onion layer. Bake in the preheated oven for 10-15 minutes or until the crust is golden brown and bubbling, watching closely to avoid burning.
Step 4: Garnish and Serve
Once baked, remove the savory French onion pizza from the oven and allow it to cool for a few minutes. Garnish with fresh thyme leaves to enhance the aromatic experience. Slice into pieces and serve warm, perfect for sharing at gatherings or simply enjoying with your family.
