If you don’t have a 9×13 pan, you can substitute two 8×8 or 9×9 square pans, one 10×15 jelly roll pan, or a 9-inch round pan plus an 8-inch round pan. The key is to match the total volume (about 2.5–3 quarts) and adjust baking time for the new pan’s depth and material.

Quick Answer

This guide covers the best bakeware sizes to substitute for a 9×13 recipe, how to adjust baking time and temperature, and tips to avoid common pitfalls.

  • Standard 9×13 volume: A typical 9×13 pan holds about 2.5 to 3 quarts (10-12 cups) of batter.
  • Best substitute: two 8×8 pans: Two 8×8 square pans have nearly the same surface area and depth, so you can bake them simultaneously at the same temperature, checking for doneness 5 minutes early.
  • Jelly roll pan alternative: A 10×15 jelly roll pan is 1 inch deep. It works for thin batters (cakes, brownies) but needs a 25% reduction in baking time. For thick batters, divide into two pans.
  • Round pan conversions: Two 9-inch round pans or one 9-inch plus one 8-inch round pan roughly match the 9×13 area. Expect slightly thicker layers and longer baking time.
  • Avoid 8×8 alone: An 8×8 pan holds only about 1.5 quarts—half the volume. Using it alone will cause overflow and underbaking. Always use two.

Understanding the 9×13 Pan Volume

A standard 9×13-inch baking dish is 2 inches deep and holds approximately 2.5 to 3 quarts (10–12 cups) of batter or liquid. This size is common for sheet cakes, brownies, casseroles, and lasagnas. When substituting, your goal is to match both the total volume and the batter depth (typically 1–1.5 inches) to ensure even baking.

If you use a pan that is too shallow (like a jelly roll pan), the batter will spread too thin and bake too quickly. If you use a deeper pan (like a loaf pan), the batter will be too thick and may not cook through. Always measure your batter volume before choosing a substitute.

Best Square Pan Substitutes

The closest substitute for a 9×13 pan is two 8×8 or 9×9 square pans. Both 8×8 pans together have a surface area of 128 square inches, nearly identical to the 9×13’s 117 square inches. The depth is the same (2 inches), so you can bake them at the same temperature as the original recipe. Check for doneness about 5 minutes early, as smaller pans may bake slightly faster.

If you only have one square pan, you can still make the recipe by halving the ingredients. Alternatively, use a 9×9 pan plus an 8×8 pan; the 9×9 holds about 2 quarts, and the 8×8 holds about 1.5 quarts—together they cover the volume. Bake the 9×9 for the full time and the 8×8 for 5 minutes less.

Round Pan and Jelly Roll Pan Options

For round pans, use two 9-inch round pans (each holds about 1.5 quarts) or one 9-inch plus one 8-inch round pan. The surface area is slightly less than a 9×13, so the batter will be a bit deeper. Bake at the same temperature but start checking 5–10 minutes later than the original recipe. If using glass or ceramic rounds, reduce the oven temperature by 25°F to prevent over-browning.

A 10×15 jelly roll pan (1 inch deep) works for thin batters like sheet cakes or brownies. Pour the batter evenly; it will be about 0.75 inches thick. Bake at the same temperature but check after 15–20 minutes (versus 25–30 for a 9×13). For casseroles or thick batters, divide the recipe between two jelly roll pans or use a different substitute.

How to Adjust Baking Time and Temperature

  1. Match the batter depth: If your substitute pan has a larger surface area (e.g., jelly roll), the batter will be thinner—reduce baking time by 20–25% and check early. If smaller (e.g., two 8×8 rounds), batter is thicker—increase time by 10–15%.
  2. Adjust for pan material: Glass and ceramic dishes retain heat longer; reduce oven temperature by 25°F and expect a slightly longer bake. Dark metal pans absorb heat faster; reduce temperature by 25°F or check 5 minutes early. Light-colored metal pans are most neutral—use the recipe temperature.
  3. Use visual and tactile cues: For cakes, a toothpick inserted in the center should come out clean or with a few moist crumbs. For casseroles, the edges should bubble and the top should be golden. Always rely on doneness tests, not just time.

Pan Material and Recipe Type Considerations

Different bakeware materials affect heat conduction. For cakes and brownies, light-colored metal pans give a tender, even crumb. Glass or ceramic dishes work well for casseroles and lasagnas but can cause cakes to brown too quickly on the bottom. If using glass for a cake, reduce the oven temperature by 25°F and place the pan on a baking sheet to insulate.

For recipes that require precise browning (like cornbread or blondies), stick with metal. For recipes that need gentle, even heat (like custards or bread puddings), glass or ceramic is better. Always place your substitute pan in the center of the oven and avoid opening the door frequently.

Pro Tips

  • When using two smaller pans, rotate them halfway through baking to ensure even browning.
  • If your substitute pan is 1 inch deep, line it with parchment paper that extends above the edges for easy removal.
  • For a 9×13 recipe that fills the pan almost to the brim (like a lava cake), avoid shallow pans—use two 9×9 pans instead.
  • Keep a kitchen scale handy to divide batter by weight if your substitute pans are different sizes.

Common Mistakes to Avoid

  • Using a single 8×8 pan for a full 9×13 recipe: batter overflows and center stays raw.
  • Assuming all 9×13 pans are 2 inches deep: some are 1.5 inches, which holds less volume. Always measure your pan’s depth.
  • Baking a thick casserole in a jelly roll pan: the shallow depth causes the top to burn before the center is hot.
  • Using glass for a delicate cake without adjusting temperature: the bottom overbakes while the top is still pale.

FAQ

Can I use a 9×13 recipe in a 10-inch springform pan?

A 10-inch springform pan holds about 2.5 quarts, similar to a 9×13. However, it is round and deeper, so the batter will be thicker. Increase baking time by 10–15 minutes and reduce oven temperature by 25°F if the pan is dark. For cheesecakes or dense batters, this works well.

What if I only have a 9×5 loaf pan?

A 9×5 loaf pan holds about 1.5 quarts—half the volume of a 9×13. You must halve the recipe. If you try to use the full recipe, the batter will overflow and the center will be raw. Halve all ingredients and bake at the same temperature for about 45–55 minutes.

How do I adjust a 9×13 recipe for an 11×7 pan?

An 11×7 pan holds about 2 quarts, which is roughly 75% of a 9×13. Reduce the recipe ingredients by 25%, or fill the pan no more than two-thirds full. Bake at the same temperature but check 5–10 minutes early, as the batter will be slightly thinner.

The Bottom Line

The best substitute for a 9×13 recipe depends on what you have on hand, but two 8×8 pans are the most reliable swap. Always measure your pan’s volume and batter depth, adjust baking time based on material and thickness, and use visual doneness cues. With these guidelines, you can confidently bake any 9×13 recipe in alternative bakeware.
