If you’re stuck with diced and need crushed, you have options. Don’t just dump them in and hope—that’s a recipe for disappointment.
Blitz them in a blender or use an immersion blender right in the can. Pulse a few times until you see a chunky puree. Congratulations—you just created impromptu crushed tomatoes.
Alternatively, simmer them longer with a splash of water and mash them with a potato masher. The calcium chloride will resist, but fifteen minutes of brute force can win the day.
Pro tip from a lazy cook: If you’re making chili or a stew where chunks are welcome, skip the blending. Diced tomatoes add a pleasant texture to hearty dishes. Lean into the chunkiness.

When You Should Never Make the Swap
Let’s be real about the hard no’s. Don’t do it for tomato soup, a delicate cream sauce, or a smooth pizza base. The chunks will violate the dish’s soul.
Also, avoid it if you’re making a quick weeknight pasta (under 20 minutes). Diced tomatoes won’t break down fast enough, leaving you with a watery sauce and random tomato cubes.
For slow-cooked dishes like Bolognese or ragu? You’re fine. The long simmer will break them down—mostly. You’ll still get a few textural surprises, but that’s called “rustic charm.”
