Bring limp, lifeless leftover pizza back to crispy, delicious life! See Chef John’s foolproof stovetop method for reheating leftover pizza so it comes out with tasty melted cheese on top and a perfectly crisp crust on the bottom (crispier than the toaster-oven method). It’s a fast method, too—no waiting around for the oven to preheat. You can also use this method to crisp-up delivery pizza that’s been steamed soggy in the box. Find the best homemade pizza recipes.
