Caramelized Onion Pan Pizza with Mozzarella

Press dough into pans about three hours before dinner—the rise time does most of the work while you do other things. Caramelized onions. Sharp cheddar. The kind of comfort food pizza that tastes like you’ve been making it for years when really it’s just waiting around and letting ingredients become themselves.

Why You’ll Love This Pan Pizza Recipe

Takes 50 minutes prep, 40 minutes baking. Total time 1 hour 30 minutes but most of it’s hands-off. The dough rests overnight in the fridge—flavor gets better, texture gets better, you just show up the next day and finish it.

One pizza feeds two people easy. Makes six at a time so leftovers are actually a thing.

Tastes nothing like frozen. Tastes nothing like delivery. Tastes like someone cared, but it’s not hard. Just methodical.

Sharp cheddar melts into the mozzarella and gets this savory edge that doesn’t feel fancy because it isn’t. It’s just good cheese doing its job.

The onions sit in white wine and sauce mix for hours—sweet but not candy sweet. Umami underneath. Thyme on top because fresh herbs matter, not because I’m trying.

Cleanup is just the pans. One pan for dough, one pan for onions, the cake tins go in the oven. Actually fine.

What You Need for Homemade Pizza Dough and Caramelized Onion Topping

Cold water. 380 ml. Sounds specific but it matters—temperature changes how fast the yeast works. Instant yeast, 8 ml. Not the packets everyone uses. Not active dry.

Unbleached all-purpose flour. 480 grams. Not bread flour. All-purpose gets crispy edges without being tough.

Fine cornmeal. 65 grams. Gives the crust a slight crunch, helps it release from the pans. Semolina works too but cornmeal’s better here.

Salt. 9 ml. Fine salt dissolves into dough, doesn’t make clumps.

Yellow onions. 850 grams chopped. That’s about six medium ones. White onions are too sharp. Red onions get weird when cooked down. Yellow ones go sweet and mild.

Vegetable oil. 50 ml. Olive oil burns at the heat you need for proper caramelization.

Ground nutmeg and white pepper. Small amounts—2.5 ml nutmeg, 3 ml white pepper. Sounds odd but onions need this. Makes them taste like more than just onions.

Dry white wine. 280 ml. Cheap’s fine. You’re cooking it down anyway. The acid balances the sweetness and the alcohol burns off.

Onion soup mix and barbecue sauce mix. One packet each. 55 grams and 45 grams. These do the seasoning work so you don’t have to guess at salt and spice levels.

Mozzarella. 550 grams shredded. Sharp cheddar. Another 550 grams. The cheddar’s the thing here—adds a flavor mozzarella alone can’t do.

Fresh thyme. Six sprigs. Not dried. Dried tastes like dust on this.

How to Make Pan Pizza Dough

Mix cold water with yeast in a bowl. Wait about three minutes. You’ll see small bubbles float up. That’s how you know the yeast’s alive and ready.

Combine flour, cornmeal, salt in a big bowl or a stand mixer with the dough hook attached. Stir in the yeast mixture. The dough will look loose and shaggy—not smooth yet. Cover it. Let it sit 20 minutes. The flour hydrates. The gluten starts relaxing on its own.

Knead by hand or with the mixer for about six minutes. The goal is smooth and elastic but not stiff and not sticky. You want soft dough. If it’s clinging to everything add a tiny bit of flour—just a pinch at a time. It’ll tell you when it’s done. You’ll feel it change.

Oil your dough ball lightly. Cover it tight. Put it in the fridge. Minimum 20 hours. I’ve tried shorter times. Less taste complexity. More bland. The long cold ferment thickens flavor in a way rushing never does.

Next day—or whenever you’re ready—take the dough out. Divide it into six equal pieces. Shape each one into a ball. Let them proof covered in a warm spot for about 60 to 70 minutes until they roughly double. Underproofed dough springs back in the oven. Overproofed dough collapses.

Oil six 15 centimeter cake pans. Press each dough ball into a pan to the edges, creating an even base all the way to the sides. Cover with a damp towel. Proof another 1.5 to 2 hours until the dough pushes back slowly when you poke it and looks puffy. Avoid cold drafts or anywhere the temperature dips. Cold stalls rising.

How to Caramelize Onions for White Wine Pizza Sauce

Heat the oil to medium in a heavy pan. Dump the onions in. Stir until they’re coated in oil. Sprinkle the nutmeg and white pepper over top.

Cover the pan. Let it cook 6 to 9 minutes. You’ll smell something sweet—that’s the onions releasing their natural sugars. Uncover it. Lower the heat to medium-low. Now the actual work begins.

Stir every few minutes. Let the onions brown evenly. Don’t rush this part. The browning is where flavor lives. Dark brown with a little stick to the pan bottom is actually good—I tap the pan with a spatula to dislodge those stuck bits because they add depth. About 20 to 30 minutes total for proper caramelization. The onions should look almost jammy.

Whisk the white wine with the onion soup mix and barbecue sauce mix in a cup until smooth. Pour it into the onions. Increase the heat slightly. Let it simmer stirring until it thickens. The sauce should coat a spoon. Takes about 10 to 12 minutes. If it’s too thin keep cooking. Taste it. Adjust salt or sweetness if something’s off.

Spread the whole mixture onto a baking sheet. Stick it in the fridge uncovered for minimum 2 hours. Hot topping on dough means softened, soggy crust. You need it cold.

Pan Pizza with Mozzarella and Cheddar Tips and Technique

Oven rack goes low. Convection oven to 220 Celsius (430 Fahrenheit). No convection? Add 10 minutes to the bake time and rotate halfway through.

Spread about 120 milliliters of the onion mixture over each dough base evenly. Not piled in the center. Spread it. Sprinkle 90 grams of mozzarella around the edges. Sharp cheddar—90 grams—goes in the center. Thyme leaves scattered across the top. One sprinkle. Not heavy.

Bake 18 to 23 minutes. Watch the cheese brown and the edges firm up. The crust should turn golden. Listen for faint bubbling. Smell matters too—both signs of doneness. Pale crust at the 20-minute mark? Nudge the oven temp up or move the pan lower on the rack.

Rest the pizzas five minutes before unmolding. The cheese sets slightly. The bottom crisps more. Gouda works instead of cheddar for a smoky edge. Fontina for a gooey melt. Cornmeal on the crust gives crunch. Semolina gives rusticity.

No barbecue sauce mix? Replace it with smoked paprika and a pinch of cayenne. Adds mild heat.

Dough too sticky to shape? Chill 10 minutes. If it fights back and won’t stretch, rest it 15 minutes uncovered so the gluten relaxes.

Limited oven space means baking them one after another. Keep finished pizzas wrapped loosely in foil to hold moisture while you bake the next batch.

Ingredients

• Dough
• 380 ml cold water
• 8 ml instant yeast
• 480 g unbleached all-purpose flour
• 65 g fine cornmeal
• 9 ml salt
• Topping
• 850 g chopped yellow onions
• 50 ml vegetable oil
• 2.5 ml ground nutmeg
• 3 ml white pepper
• 280 ml dry white wine
• 1 packet (55 g) onion soup mix
• 1 packet (45 g) barbecue sauce mix
• 550 g shredded mozzarella
• 550 g shredded sharp cheddar
• 6 sprigs fresh thyme leaves

Method

1. Dough Preparation
2. 1 Mix water with yeast until foamy, about 3 minutes. Float small bubbles signal active yeast.
3. 2 Combine flour, cornmeal, salt in a big bowl or stand mixer with dough hook. Stir in yeast mixture. Expect a loose dough; rest 20 minutes to hydrate and rest gluten. Notice slight tackiness before kneading.
4. 3 Knead by hand or mixer about 6 minutes until smooth but not sticky. Use flour sparingly; dough should be soft and elastic not stiff.
5. 4 Form dough into a ball, oil lightly, cover tightly. Refrigerate minimum 20 hours. This long cold ferment thickens flavor, improves chew. I've tried shorter times—less taste complexity, more bland.
6. 5 Before using, divide dough into 6 equal pieces. Shape each into smaller balls. Let proof covered 60–70 minutes in warm spot until doubles. No rush here. Dough that’s underproofed springs back; overproofed collapses in oven.
7. 6 Lightly oil six 15 cm cake pans. Press dough balls into pans to edges, create even base. Cover again with damp towel. Proof another 1.5 to 2 hours until dough pushes back slowly and puffy. Avoid cold drafts; stalls rising.
8. 7
9. Cooking the Topping
10. 8 Heat oil medium in heavy pan. Toss in onions, stir to coat. Sprinkle nutmeg and white pepper.
11. 9 Cover, cook 6–9 minutes until softened, releasing sweet onion aroma. Uncover, lower heat to medium-low. Stir every few minutes, let onions caramelize evenly—don't rush. Avoid burning by adjusting heat; dark brown with a little stick to pan is good. I tap pan bottom with spatula to dislodge stuck bits—adds flavor.
12. 10 In cup, whisk wine with onion soup and barbecue sauce mixes until smooth.
13. 11 Add wine mix to onions. Increase heat slightly, simmer stirring until thickening—sauce coats spoon. About 10–12 minutes here. If too thin, cook longer. Taste to balance salt and sweetness.
14. 12 Cool mixture fully in fridge minimum 2 hours. Hot topping on dough? Problem. Softens too much, makes crust soggy.
15. 13
16. Baking
17. 14 Place oven rack low. Preheat convection oven to 220 C (430 F). If no convection, add 10 minutes to bake time and rotate halfway.
18. 15 Spread 120 ml (just under ½ cup) onion mixture per crust evenly over dough. Sprinkle 90 g mozzarella around edges, sharp cheddar 90 g in center. Leaves thyme over top.
19. 16 Pop in oven. Bake 18–23 minutes watching cheese brown, edges firm up, crust turning golden. Listen for faint bubbling and scent—both signs of doneness. If crust edges pale at 20-minute mark, nudge oven temp slightly upward or move pan lower.
20. 17 Rest pizzas 5 minutes before unmolding. Cheese will set slightly, doh will crisp more at bottom.
21. 18
22. Extras and Tips
23. 19 Swap cheddar for aged gouda for smoky edge, or part fontina for gooey melt. Substitute cornmeal with semolina or polenta based on texture preference; I prefer cornmeal for slight crunch but semolina adds rustic graininess.
24. 20 If no barbecue sauce mix, replace with smoked paprika and a pinch of cayenne. Adds mild heat and complexity.
25. 21 Too sticky dough? Chill 10 minutes before shaping. If dough tight and resists stretch, let rest 15 minutes uncovered to relax gluten.
26. 22 To speed topping cooling, spread on baking sheet thin layer, then refrigerate uncovered to avoid clumps.
27. 23 If oven space limited, bake pizzas one after another; keep cooked pizzas wrapped loosely in foil to maintain moisture.

Frequently Asked Questions About Homemade Pan Pizza

Can I use instant yeast or do I need active dry? Instant works. Actually prefer it here—faster, more reliable. Active dry takes longer, needs a different hydration ratio. Not worth switching.

Why overnight in the fridge for the dough? Cold fermentation develops flavor. Enzymes work slower. Gluten gets stronger. It’s the difference between bland and complex. You can skip it but why would you.

Can I make the caramelized onions ahead of time? Days ahead. Tastes better after sitting. Just keep it cold. Reheat gently if it’s gotten stiff.

What if my oven doesn’t have convection? Add 10 minutes to the bake time. Rotate the pan halfway. Check at the 20-minute mark for browning. Convection’s not essential, just faster.

How do I know when the crust is done? Golden edges. Listen for bubbling. Smell—it’ll smell done before it looks done. Bottom should be firm. Tap it. Sounds hollow underneath. Takes practice but you’ll feel it.

Can I use a different cheese? Yeah. But the sharp cheddar’s doing work here—don’t lose that. Gouda adds smoke. Fontina adds melt. Don’t use just mozzarella or it’s flat and bland.
