Pro Tips Before You start
1. Don’t rush the onions.
This is the number one mistake. Caramelizing onions takes patience. If your onions look done after 5 minutes, they’re not. Give them the full time.
2. Slice your onions thin and even.
Uneven slices caramelize at different speeds. Some will burn while others are still raw. Take the extra 2 minutes to slice them properly.
3. Preheat your oven fully before the pizza goes in.
A cold or half-warm oven gives you a soggy crust. Let that oven hit 425°F completely before it touches the pizza.
4. Layer the mozzarella first, not last.
Mozzarella under the onions helps hold everything together. Gruyere goes on top so it gets that golden, slightly crispy edge.
5. Broil for the last minute, but watch it like a hawk.
This is where the magic happens. It’s also where pizzas go from perfect to burnt in about 15 seconds. Stand there and watch.

The Most Cheesy French Onion Soup Pizza

1 large pizza dough or crust of your choice
– 3 medium sweet onions, thinly sliced
– 2 tablespoons extra virgin olive oil
– 1 tablespoon coconut sugar (or brown sugar)
– 1 cup fresh mozzarella, sliced or shredded
- 3/4 cup shredded gruyere cheese
– Fresh thyme, for garnish
– Red pepper flakes, optional but recommended
Instructions
- 1. Warm the olive oil in a largeskillet over medium-highheat. Add the sliced onions and cook for about 3 minutes,stirring occasionally.
- 2. Cover the onions and let them simmer for 10 minutes, stirring every couple of minutes so they don't stick.

- 6. Bake for 10 minutes, then switch to broil for 1 to 2 minutes if you want that bubbly, golden cheese top. Watch closely so it doesn't burn.

Make Ahead Tips
The onions are the part that takes the longest, so make them the hero of your prep.
-Caramelize the onions up to 3 days ahead and store them in the fridge in an airtight container.
– When you’re ready for pizza night, just reheat the onions slightly in a pan and assemble.
– This turns a 25 minute recipe into more like a 12 minute one on the night you actually want to eat it.

FAQs:
Can I use a store-bought crust?
Yes. I use a frozen crust from the grocery store almost every time. No shame in that game.
Why aren’t my onions caramelizing?
Your heat is probably too high or your onions are too crowded in the pan. Caramelizing is a slow, gentle process. Turn the heat down and give them room to breathe.
Can I make this into individual mini pizzas?
Absolutely. Use naan bread or small personal crusts and reduce the bake time to about 7 minutes.
Is this recipe kid friendly?
Mine loves it, minus the red pepper flakes. The sweetness from the caramelized onions makes it more approachable than you’d think for picky eaters.
