Reheat Detroit Style Pizza in the Oven for a Crisp Crust

Detroit-style pizza is a rectangular, thick-crust pizza with a chewy interior, crisp cheese-browned edges, and toppings often finished with stripes of tomato sauce. To reheat a slice in the oven, warm it gently first, then uncover it briefly so the base crisps without drying out the cheese or crust.

Ingredients

2 slices refrigerated Detroit-style pizza, about 8 oz (225 g) total
1 teaspoon water (5 ml), for creating steam in the covered pan
1 teaspoon olive oil (5 ml), optional, for the pan

Instructions

Preheat the oven. Set a rack in the center and heat the oven to 375°F (190°C). Let it preheat fully; a steady oven temperature helps warm the thick center before the edges become too dark.
Prepare the slices. Take the pizza from the refrigerator and separate the slices if they are stuck together. If the pan is prone to sticking, lightly coat a small oven-safe skillet or baking dish with the olive oil. Arrange the slices in one layer, leaving a little space between them. A metal pan gives the bottom a particularly crisp finish; a ceramic dish heats more gently.
Cover and warm. Sprinkle the teaspoon of water into an empty corner of the pan, away from the pizza. Cover the pan tightly with foil, taking care not to press the foil onto the toppings. Bake for 6 minutes. The trapped steam helps warm the thick dough and cheese evenly instead of leaving the center cold while the outside dries out.
Uncover and crisp. Remove the foil carefully, as escaping steam is hot. Continue baking for 3 to 5 minutes, until the cheese is hot and the underside is crisp. Check after 3 minutes; ovens, slice thickness, and topping amounts vary. If the bottom is not crisp enough, give it another minute or two. Avoid switching to broil unless you watch closely, because the cheese and sauce can scorch quickly.
Check the temperature and serve. For safe leftover handling, use an instant-read thermometer in the thickest part of a slice without touching the pan. The USDA FSIS safe minimum for reheated leftovers is 165°F (74°C). If it has not reached that temperature, return it to the oven for 1 to 2 minutes and check again. Rest for 1 minute before eating; the cheese and pan will be very hot.

Tips

Adjust for a whole pie or extra-thick pieces. This timing is for two refrigerated slices. A larger portion needs more time; keep it covered until hot through, then uncover to crisp. Check the center with a thermometer rather than relying only on browned cheese.
Skip excess water. One teaspoon is enough for a small pan. Water poured on the crust or toppings can make them soggy, while too much steam prevents the bottom from crisping.
Use a rack if you prefer less-crisp bottoms. Set slices on a wire rack over a baking sheet and bake uncovered at 375°F (190°C), checking after 8 minutes. This gives more even airflow but will not crisp the base as strongly as a preheated metal pan.
Keep toppings in place. If sauce or cheese is loose, use a spatula to transfer each slice and avoid crowding the pan. Do not add extra sauce before reheating; serve it alongside instead.

Serving Suggestions

Serve the slices hot, with a simple green salad dressed in vinaigrette to balance the rich cheese and sturdy crust. A small bowl of warm marinara or pizza sauce works well for dipping, especially if the original slices have only a light sauce finish. For a casual meal, add roasted vegetables, a chopped salad, or a bowl of soup. Finish with a pinch of dried oregano or red pepper flakes if desired, but taste first: Detroit-style pizza can already be generously seasoned.

Let the slices rest briefly before serving so the cheese settles and the bottom stays crisp. If reheating several slices, transfer finished pieces to a warm platter rather than stacking them; stacking traps steam and softens the crust.

Variations

Extra-crisp finish: After the covered warming stage, move the slices to a preheated, lightly oiled cast-iron skillet and cook over medium-low heat for 1 to 2 minutes. Watch closely and stop once the base is crisp; this adds a stovetop step, so it is optional.
Gentler reheat: For slices with delicate vegetables or a thick layer of cheese, keep the oven at 350°F (175°C) and leave them covered for 7 to 9 minutes, then uncover for 2 to 3 minutes. The slower heat reduces the chance of over-browning.
Frozen slices: For best texture, thaw in the refrigerator overnight, then use the method above. If baking from frozen, use 350°F (175°C), keep the slices covered until the center is hot, and expect the total time to increase; check the thickest part for 165°F (74°C).
Different toppings: Pepperoni, vegetables, and extra cheese can all be reheated with the same method. Remove any fresh greens or herbs before heating and add them afterward. A very heavily topped slice may need an extra minute or two.

Storage and Reheating

Refrigerate leftover pizza within 2 hours of serving, in a shallow airtight container or wrapped securely. Properly refrigerated cooked pizza keeps for 3 to 4 days. If it has been left at room temperature for more than 2 hours—or more than 1 hour in temperatures above 90°F (32°C)—discard it rather than trying to make it safe by reheating.

For longer storage, freeze slices in a freezer-safe container or wrap them individually, separating layers with parchment. For best quality, use frozen leftovers within about 1 to 2 months. Thaw overnight in the refrigerator when convenient; do not thaw pizza on the counter. Reheat only the number of slices you plan to eat, and bring leftovers to 165°F (74°C), checked with a food thermometer. Avoid repeatedly cooling and reheating the same portion, as each cycle can reduce quality and adds food-safety risk.

Frequently Asked Questions

What temperature is best for reheating Detroit-style pizza?
Use 375°F (190°C) for refrigerated slices. Covering the pan at first warms the thick crust, and uncovering it near the end lets the edges crisp. For delicate or heavily topped slices, 350°F (175°C) is a gentler alternative.

How long does it take to reheat a slice in the oven?
Allow about 9 to 11 minutes at 375°F (190°C): 6 minutes covered, then 3 to 5 minutes uncovered. Thick slices or a crowded pan may take longer. The reliable check is 165°F (74°C) in the thickest part.

Should I put Detroit-style pizza directly on the oven rack?
It is better to use a baking sheet, skillet, or oven-safe dish. The thick, cheesy edges can sag or drip through an oven rack, and a pan makes it easier to collect melted cheese and sauce.

Can I reheat it without foil?
Yes. Bake uncovered at 375°F (190°C), checking after about 7 minutes. The crust may crisp sooner, but the cheese and edges can dry before the center warms, so watch the slices and use a thermometer when possible.

Can I reheat Detroit-style pizza more than once?
It is safest and best for texture to reheat only what you will eat. Keep the rest refrigerated and avoid repeated warming and cooling; any portion you do reheat should reach 165°F (74°C).

Why did my crust turn soggy?
Common causes include adding too much water, covering the pizza for the entire bake, or stacking slices while they are hot. Use only a teaspoon of water for steam, uncover for the final few minutes, and serve slices in a single layer.
