Vegan Lasagna
About this recipe
Italian cooking is built on time-honoured regional traditions — pasta from the south, risotto from the north, the everyday economy of a Tuscan kitchen — where simplicity, seasonality, and respect for the produce typically matter more than complexity of technique.
As a vegan dish, Vegan Lasagna is built without animal products — and the technique compensates for what dairy or meat would normally contribute, leaning on browning, roasting, fermentation, and umami-rich ingredients.
The scaler above resizes every ingredient to the number of servings you actually want; Cook Mode walks you through the recipe one step at a time with hands-free timers.

Method
- 1) Preheat oven to 180 degrees celcius.
- 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) Blanch spinach leaves for a few minutes in a pan, before removing and setting aside.
- 4) Top up the pan with water and cook the lasagne sheets. When cooked, drain and set aside.
- 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) Bake in the preheated oven for about 25 minutes.
Cooking notes
Most vegetable dishes scale linearly, but be mindful of pan crowding — vegetables that should brown will steam instead if packed too tightly.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Vegan Lasagna
Vegan Lasagna is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Plant-based dishes are typically the most forgiving to scale. Vegan Lasagna uses ingredients that scale almost entirely linearly; the main considerations are pan capacity (don't crowd vegetables — they steam instead of browning) and seasoning (use 1.5× the salt and spices when doubling). Cooking time barely changes for sautés and sheet-pan preparations.
When you scale the flour in this recipe, weigh it in grams if you can — a cup of flour can weigh anywhere from 113 g to 150 g depending on how you measure. The ScaleRecipe ingredient converter uses the King Arthur Baking reference of 120 g/cup for all-purpose flour, which is the same standard most modern baking books assume.
Butter is one of the easier ingredients to scale because it's sold in standardised sticks: 1 US stick = 8 tablespoons = ½ cup = 113 g. Any fractional scaling lines up neatly on a kitchen scale, and grocery-store butter packaging is already pre-marked in tablespoon increments along the wrapper.

Beyond the recipe
Substitutions & make-ahead — Vegan Lasagna
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Vegan Lasagna is doing structurally — here's the practical version.
Substitution ideas
Butter
For sautéing or browning, equal-weight olive oil or a neutral oil works directly. For baking, equal-weight coconut oil (melted, then chilled to the same softness the recipe expects) gives a buttery richness; a quality vegan butter brick is the structural match for cookies and pastries where firmness matters.
Dairy milk
Unsweetened soy milk substitutes 1:1 in custards and baked goods (the protein content matches). Oat milk gives a creamier mouthfeel for soups and coffee drinks. Almond milk works for lighter applications. Skip coconut milk in savoury recipes unless the dish calls for it — the flavour is unmistakable.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Plant-based dishes generally store better than animal-protein recipes — there's no cooked-meat texture degradation to worry about. Vegan Lasagna keeps well refrigerated for 3-4 days. The main thing to watch is texture: leafy greens wilt, raw crunchy elements soften, croutons go limp. Add those at serving time rather than at the day-of cook. Pulse and legume-based dishes (beans, lentils) often genuinely improve overnight as spices marry.
