Yield: 1 12-inch pizza


  • 1 lb pizza dough homemade or store bought
  • 7 slices bacon (7 oz), cooked and chopped
  • 3 Tbsp olive oil , divided
  • 8 oz baby spinach
  • 1 large red onion , sliced 1/4-inch thick slices
  • Salt and freshly ground black pepper
  • 1 tsp granulated sugar
  • 1 Tbsp balsamic vinegar
  • 2 Tbsp butter
  • 1 large clove garlic
  • 2 Tbsp flour
  • 3/4 cup milk
  • 6 oz low-moisture mozzarella cheese , shredded
  • 2 oz parmesan cheese , finely shredded


  1. Place a pizza stone in oven and preheat oven to 475 degrees.

  2. Heat 1 Tbsp olive oil in a large skillet over medium-high heat. Add spinach and saute just until wilted. Transfer to several layers of paper towels and squeeze some of the excess liquid from spinach, set aside.
  3. Add another 1 Tbsp olive oil to skillet and set over medium heat. Add onions, season lightly with salt and saute 10 minutes. Add sugar and cook until they begin to caramelize, about 5 - 10 minutes longer, adding a few tbsp water as needed to prevent them from drying and burning. Stir in balsamic vinegar and cook 1 minute longer, set aside.
  4. Shape pizza dough into a 12-inch round over a lightly floured surface, leaving a larger rim around edge of dough for crust. Brush top with remaining 1 Tbsp olive oil and let rest 10 minutes.

  5. In a small saucepan, melt butter over medium heat. Add flour and garlic and cook, stirring constantly, 1 minute. While whisking, slowly pour milk into flour mixture. Season with salt and pepper to taste and bring mixture just to a boil stirring constantly then remove from heat.
  6. Spread white sauce evenly over pizza, leaving crust uncoated. Top with half of the mozzarella and half of the parmesan, then add spinach, bacon and onions. Top with remaining half of the mozzarella and parmesan. Using a pizza peel, transfer pizza to preheated pizza stone and bake in preheated oven 8 - 12 minutes until cheese is melted and crust is golden.

    I did substitute cooked Hot Italian sausage for the bacon and my husband was thrilled. Next time I will use the bacon. Variety is the spice of life.

  • Deb: This was so good! I never had a pizza like this before but decided to give it a try because I had all the ingredients in the house and was out of the usual toppings I use. Your instructions were easy to follow. It was a little time consuming to make but well worth the extra effort. We loved the flavor and will definitely be making this again soon.

    • Jaclyn: Thanks for bringing that up, I’ve actually found that a pizza stone works best and no parchment is necessary so I’ve updated the recipe :). Hope you love it! November 19, 2017 at 10:23pm Reply

  • Lindy: Hi Jaclyn, I would like to know if the toppings, including the sauce, can be made a few hours ahead as I’d love to make this at our pizza night?
