Tips For Making This Recipe.

caramelizing onions

This is a pretty easy pizza recipe, so there’s not a lot to warn you about. Make sure not to burn the onions, but other than that there’s not a lot that you can do to ruin this one!

When you’re cooking the onions, make sure to keep them moving, or they’ll burn and taste bitter.

With the onions, make sure to slice them pretty evenly, but you don’t need to make them super-thin. I used a sweet Vidalia onion, but you can use any kind if you like a stronger flavor.

Oil the pizza pan well before putting the pizza dough in, and give yourself time to press it into the pan. If the gluten is too strong in the dough it will spring back, so press it into the pan then let it relax for a while and keep shaping it.

Letting it rest will let the gluten relax and the dough won’t fight you when you press it out.

I used half of each bell pepper, but you can use as much of each color as you’d like to. You can also roast the peppers then slice them and put them on the pizza instead of sauteing them.

Spreading tomato sauce on the dough

If you want to add some pizza sauce, do that before putting the onions on the dough. If the tomatoes that you use aren’t really ripe, it can improve the flavor to add a little sauce to the mix.

If you use a cheese blend, provolone is a good one to include. I used a basic 6-cheese Italian blend from the supermarket.
