This vegetable lasagna cooks entirely on the stove top—no oven required.
When blending the hot tomato sauce, ensure you release steam by removing the center cap of the blender lid and covering with a cloth, or use an immersion blender directly in the pot to prevent pressure buildup. The no-bake lasagna noodles are delicate; handle them carefully to avoid breakage when layering. For optimal flavor, use very ripe, sweet tomatoes. If unavailable, canned diced tomatoes (drained) can be used as a substitute, but the fresh quality enhances this simple dish. Adjust seasoning throughout the layering process to build flavor. Allowing the lasagna to rest after cooking is crucial; it allows the layers to set, making for cleaner slices and preventing it from falling apart.
