Vegan Lasagna

Why this dinner works

Most weeknight one-pot dinners ask you to choose between two evils: a five-ingredient bowl that tastes like the inside of a saucepan, or a recipe so layered it eats your entire evening. Vegan Lasagna sits comfortably in the middle. It draws on Italian traditions where building flavor in stages — aromatics, then spice, then the slow swell of liquid into starch — is just how dinner gets made on a regular Tuesday.

The whole thing comes together in about 51 minutes in a single soup pot, which means dinner from idea to table is shorter than most podcast episodes. We've leaned on the everyday 12 ingredients listed below, but in the notes after the recipe you'll find the small swaps and shortcuts that make this dish forgiving when your fridge is half-empty.

Method

1. Step 1. 1) Preheat oven to 180 degrees celcius.
2. Step 2. 2) Boil vegetables for 5-7 minutes, until soft. Add lentils and bring to a gentle simmer, adding a stock cube if desired. Continue cooking and stirring until the lentils are soft, which should take about 20 minutes.
3. Step 3. 3) Blanch spinach leaves for a few minutes in a pan, before removing and setting aside.
4. Step 4. 4) Top up the pan with water and cook the lasagne sheets. When cooked, drain and set aside.
5. Step 5. 5) To make the sauce, melt the butter and add the flour, then gradually add the soya milk along with the mustard and the vinegar. Cook and stir until smooth and then assemble the lasagne as desired in a baking dish.
6. Step 6. 6) Bake in the preheated oven for about 25 minutes.

Cook's notes

One pan, fewer dishes. Use the widest, heaviest soup pot you own with a tight-fitting lid. The wider base means faster browning at the start; the lid traps the gentle steam that finishes the dish without scorching the bottom.

Salt as you go. Season the aromatics, season the protein, season the liquid before it reduces. By the time you taste at the end, the only adjustment is usually acid — a squeeze of lemon, a splash of vinegar, a final crack of pepper.

Make it ahead. Like most one-pot dinners with italian roots, the leftovers are arguably better the next day. Cool quickly, refrigerate within two hours, and reheat gently with a splash of water or stock to loosen things back up.

Pairings & serving

This one feels best in a 6-bowl spread with a sharp green salad and something cold to drink. If you want to stretch it for unexpected company, double the liquid and a single starchy ingredient — rice, pasta, potatoes, depending on the recipe — and the whole pan grows without much extra work.
