French Onion Soup Pizza With Turkey Bacon And Chicken Ham
This French Onion Soup Pizza features deeply caramelized onions, Gruyère and mozzarella cheeses, turkey bacon, and chicken ham on a crispy crust.
Ingredients
For the Caramelized Onions:
- 3 large yellow onions (2 lbs / 900g), thinly sliced
- 2 tbsp (30g) unsalted butter
- 1 tbsp (15ml) olive oil
- 1/2 tsp (2.5g) fine sea salt
- 1/4 tsp (1g) granulated sugar
- 1/4 cup (60ml) beef broth, low sodium
- 1 tbsp (15ml) balsamic vinegar
For the Pizza:
- 1 lb (450g) pre-made pizza dough, at room temperature
- 1 tbsp (15ml) olive oil
- 4 oz (115g) turkey bacon, cooked crisp, crumbled
- 4 oz (115g) chicken ham, diced 1/2-inch (1.25cm)
- 6 oz (170g) Gruyère cheese, shredded
- 4 oz (115g) low-moisture mozzarella cheese, shredded
- 1 tbsp (5g) fresh thyme leaves, picked
- 1/4 tsp (1g) freshly ground black pepper
- 1/8 tsp (0.5g) red pepper flakes (optional)
Instructions
- Heat a large, heavy-bottomed pan or Dutch oven over medium-low heat. Add 2 tbsp (30g) unsalted butter and 1 tbsp (15ml) olive oil, melting until shimmering.
- Add 3 large yellow onions, thinly sliced, to the pan along with 1/2 tsp (2.5g) fine sea salt and 1/4 tsp (1g) granulated sugar. Stir to coat onions evenly.
- Cover the pan and cook for 15 minutes, stirring occasionally, until onions soften and release moisture.
- Uncover the pan, reduce heat to low, and cook onions for 45-60 minutes, stirring every 5-7 minutes, until deep golden brown and jam-like.
- Pour in 1/4 cup (60ml) low-sodium beef broth and 1 tbsp (15ml) balsamic vinegar. Scrape up any browned bits from the pan bottom. Cook for 2-3 minutes until liquid evaporates and onions are glossy. Remove from heat; set aside.
- Preheat oven to 450°F (230°C). If using a pizza stone or steel, place it in the oven for at least 30 minutes during preheating.
- Cook 4 oz (115g) turkey bacon until crisp; drain fat, then crumble. Dice 4 oz (115g) chicken ham into 1/2-inch (1.25cm) pieces.
- Shred 6 oz (170g) Gruyère cheese and 4 oz (115g) low-moisture mozzarella cheese. Combine in a bowl.
- Lightly flour a pizza peel or large baking sheet. Stretch or roll 1 lb (450g) pre-made pizza dough into a 12-14 inch (30-35cm) circle. Brush dough edges with 1 tbsp (15ml) olive oil.
- Evenly spread cooled caramelized onions over the pizza dough, leaving a 1/2-inch (1.25cm) border.
- Sprinkle crumbled turkey bacon and diced chicken ham over the caramelized onions.
- Spread the shredded Gruyère and mozzarella cheese mixture over the toppings.
- Sprinkle 1 tbsp (5g) fresh thyme leaves, 1/4 tsp (1g) freshly ground black pepper, and 1/8 tsp (0.5g) red pepper flakes (optional) over the cheese.
- Transfer pizza to the preheated pizza stone/steel or place the baking sheet directly into the oven. Bake for 12-17 minutes, rotating halfway through, until crust is golden brown and crispy, and cheese is bubbly and lightly browned.
- Remove pizza from oven. Rest 2-3 minutes on a cutting board before slicing. Slice into 8 pieces and serve immediately.
Notes
- Maintain low heat and stir onions frequently for proper caramelization.
- Bring pizza dough to room temperature for at least 30 minutes before stretching for optimal pliability.
- Freshly grate Gruyère and mozzarella cheese for best melt and flavor.
- Brush stretched pizza dough with a thin layer of olive oil before adding onions for an extra crispy crust.
- Prepare caramelized onions up to 3 days in advance; store in an airtight container in the refrigerator.
Pro Tips for Perfect French Onion Soup Pizza
Ingredient Tips
- Onion Slicing Technique:Slice 4-5 large yellow onions (about 3 lbs total) uniformly thin, 1/8-inch thick, using a mandoline if possible for consistent caramelization. This ensures all onions cook evenly and reach a deep golden brown together.
- Broth Reduction for Base:Reduce 2 cups of high-quality beef or vegetable broth (low sodium) by half, simmering gently over medium-low heat for 15-20 minutes until 1 cup remains and it coats the back of a spoon. This intensifies the umami base without making the pizza soggy.
- Dry White Wine Selection:Use 1/2 cup of a dry white wine like Sauvignon Blanc or Pinot Grigio. Deglaze the pan with it immediately after onions are soft, simmering for 2-3 minutes until 90% evaporated and the alcohol aroma mellows. This adds essential acidity and depth to the onion base.
- Optimized Cheese Blend:Combine 4 ounces of freshly grated Gruyère with 3 ounces of low-moisture, part-skim mozzarella. The Gruyère provides nutty complexity, while the mozzarella ensures a smooth, stretchy melt and even coverage when baked at 425°F for 12-15 minutes.
- Turkey Bacon Crisping:Cook 6 slices of turkey bacon in a non-stick pan over medium heat for 8-10 minutes, flipping frequently, until deeply golden brown and crisp, then drain on paper towels. This removes excess fat and prevents a chewy texture on the finished pizza.
- Chicken Ham Preparation:Dice 4 ounces of cooked chicken ham into uniform 1/4-inch cubes. Smaller pieces distribute flavor evenly across the pizza and prevent large, rubbery chunks, ensuring every bite has a savory ham presence.
Technique Tips
- Slow Onion Caramelization:Cook 3 lbs of thinly sliced yellow onions in 3 tablespoons of unsalted butter over medium-low heat (stove setting 3-4 out of 10) for 45-60 minutes, stirring every 5-7 minutes. They should gradually soften, turn a deep amber-brown, and become jam-like, sliding off a spoon without resistance, indicating full sweetness development.
- Preheating Pizza Stone/Steel:Place your pizza stone or steel in the oven and preheat at 500°F (260°C) for at least 30-45 minutes. A super-hot surface is crucial for achieving a crisp bottom crust within 8-12 minutes, preventing sogginess.
- Strategic Pizza Layering:Apply a thin, even layer (2-3 tablespoons) of the reduced broth “sauce” first, leaving a 1-inch border. Then spread 1 cup of caramelized onions, followed by 1/2 cup of chopped chicken ham, 1/4 cup of crumbled turkey bacon, and finally 7 ounces of cheese blend. This layering ensures even heat distribution and optimal flavor balance.
- High-Heat Baking Duration:Bake the assembled pizza on the preheated stone/steel at 475°F (245°C) for 10-14 minutes. The crust should be golden brown, the cheese fully melted and bubbling at the edges with some browned spots, and all toppings heated through.
Common Issues
- Soggy Crust:To prevent a soggy crust, ensure your pizza dough is rolled to an even 1/4-inch thickness. Blind bake the crust for 5-7 minutes at 400°F (200°C) before adding toppings, or use a pizza stone preheated for 45 minutes at 500°F (260°C) to ensure a rapid, crisp bottom bake.
- Under-Caramelized Onions:If your onions aren’t deeply colored after 45 minutes, add 1 teaspoon of granulated sugar and continue cooking on low heat (setting 2-3) for another 15-20 minutes, stirring frequently. The sugar will aid in browning and deepen the sweetness.
- Lack of “Soup” Flavor:If the French onion flavor isn’t prominent, whisk 1/4 teaspoon of dried thyme and a pinch of black pepper into your reduced broth base. Optionally, after spreading the onions, sprinkle an additional 1/8 teaspoon of garlic powder evenly over them before adding cheese.
- Cheese Not Browning:If the cheese isn’t browning sufficiently after 12 minutes, switch the oven to broil on high for the last 1-2 minutes, watching constantly. Position the pizza on the top rack until the cheese develops appetizing golden-brown spots and edges are bubbling vigorously.
How to Store and Reheat French Onion Soup Pizza
Refrigerator Storage
Duration: 3-4 days in airtight container
For optimal quality and safety, store leftover French Onion Soup Pizza in an airtight glass container or wrapped tightly in aluminum foil, then placed in a sealed bag. This prevents the absorption of other refrigerator odors and helps maintain moisture. The crispy crust will inevitably soften over time, absorbing moisture from the savory caramelized onion base and cheese. The Gruyère and mozzarella will firm up and lose their fresh melt-and-stretch quality, while the turkey bacon and chicken ham may become less crisp. For the best possible texture, consume within 2 days. Beyond day 3, while still safe, the flavor profile can dull, and the overall texture will become noticeably chewier and less appealing.
Freezer Storage
Duration: 1-2 months
To freeze, ensure the pizza slices are completely cooled. Individually wrap each cold slice first in plastic wrap, then in a layer of heavy-duty aluminum foil, and finally place them into a freezer-safe zip-top bag, expelling as much air as possible. This triple layer of protection is crucial to prevent freezer burn and flavor degradation. For best results, thaw individual slices overnight in the refrigerator (approximately 8-12 hours) before reheating. Slices can be reheated from frozen, but will require longer cooking times and might result in a slightly soggier crust due to the melting of ice crystals. Expect the texture of the caramelized onions to be slightly softer and the crust to lose some of its original crispness, becoming chewier upon reheating from frozen.
Reheating Instructions
- Oven (Recommended for Best Quality):Preheat oven to 375°F (190°C). Place pizza slices directly on a baking sheet or a wire rack. Reheat for 12-18 minutes, or until the cheese is bubbling and lightly golden, and the crust is crisp to your liking. For frozen slices, extend cooking time to 20-25 minutes. This method is superior for restoring the original crispness of the crust and ensuring even heating.
- Air Fryer (Excellent for Individual Slices):Preheat air fryer to 350°F (175°C). Place 1-2 slices in a single layer in the air fryer basket. Cook for 5-8 minutes, checking periodically, until the cheese is fully melted and bubbly, and the crust is deliciously crispy. For frozen slices, add an additional 5-7 minutes. This method excels at producing a very crisp crust quickly.
- Skillet (Good for a Crispy Bottom):Place a non-stick skillet over medium-low heat. Add pizza slices directly to the dry pan. Cover the skillet with a lid (or tent with aluminum foil) and cook for 6-10 minutes, or until the bottom crust is golden and crisp, and the cheese has thoroughly melted. Covering helps to steam the cheese, ensuring it melts without burning the bottom crust.
- Microwave (Quickest, but Compromises Quality):Place a single slice on a microwave-safe plate. Heat on high for 45-90 seconds, or until the cheese is melted and warm to the touch. While incredibly fast, this method results in a significantly soft, chewy, and often rubbery crust, sacrificing the desirable texture. Use only if time is severely limited and texture is not a primary concern.
Make-Ahead Tips
Preparing components of your French Onion Soup Pizza in advance can greatly simplify assembly. The most time-consuming element, the caramelized onions, can be prepared up to 3 days in advance and stored in an airtight glass container in the refrigerator; their flavor often deepens over time. The cheese blend (shredded Gruyère and mozzarella) can be mixed 1-2 days ahead and kept in a sealed plastic bag or container in the fridge. Cooked and crumbled turkey bacon, along with diced chicken ham, can also be prepared 1-2 days prior and stored separately in airtight containers in the refrigerator. If making your own pizza dough, prepare it a day in advance and store it tightly wrapped in the refrigerator, allowing it to warm slightly before stretching. For a head start, you can par-bake your crust for 5-7 minutes, let it cool completely, then wrap tightly and store at room temperature for up to 1 day, or freeze for longer, adding toppings just before the final bake.
