For a vegetarian lasagne, the tomatoes, spinach or other leafy greens, and cheese are the priority ingredients for going organic. Tomato sauces and passata are often made from intensively grown crops, so organic options reduce pesticide residues in these concentrated products.
Leafy greens can also carry more residues on their surfaces, while organic cheese supports dairy farms that manage land with fewer synthetic inputs. When lasagne becomes a regular crowd-pleaser, swapping core ingredients to organic is a straightforward way to improve the baseline quality.
