Plant-Based Meal Prep: A Complete Week of Vegan Meals Ready in 90 Minutes

Plant-based meal prep succeeds because whole-food vegan ingredients — legumes, grains, roasted vegetables, nuts and seeds — are among the best batch-cooking ingredients in existence. Lentil dal improves after two days in the fridge. A baked tofu block holds its texture for four days. Roasted chickpeas stay crispy for three days stored at room temperature in a jar. Grain salads with quinoa or farro actually get better as the dressing absorbs over time. These are not delicate proteins that degrade quickly — they are robust, flavour-deepening, prep-friendly foods. The nutritional argument for plant-based eating is well-established: large-scale studies including the EPIC-Oxford cohort study find that vegan diets are associated with lower rates of cardiovascular disease, type 2 diabetes and certain cancers, alongside a significantly reduced environmental footprint. However, for these benefits to materialise, the diet must be well-planned — specifically around protein, vitamin B12, iron, calcium, omega-3 fatty acids and zinc. Meal prep enables this planning. When you are building your containers on Sunday with nutritional intention — balancing legumes for protein and iron, adding fortified plant milk for calcium and B12, sprinkling seeds for zinc and omega-3 — you are creating a week of nutritionally complete eating with a single focused effort. The alternative — improvising plant-based meals daily — is where nutritional gaps and calorie shortfalls are most likely to occur.

This list is designed for one person targeting approximately 1,800–2,000 kcal per day on a fully plant-based diet, with particular attention to protein completeness. Proteins and legumes: 500 g firm tofu (extra-firm if available), 2 x 400 g tins chickpeas, 400 g dry green lentils (or Puy lentils), 400 g dry red lentils, 400 g tin cannellini beans. Grains: 400 g dry quinoa, 500 g dry brown rice, 400 g dry oats. Vegetables: 1 bag frozen broccoli (500 g), 1 bag frozen edamame (500 g), 2 large sweet potatoes, 1 bunch kale (or 200 g frozen kale), 2 bell peppers, 3 medium courgettes, 4 cloves garlic, 2 red onions, 1 x 400 g tin chopped tomatoes. Nuts, seeds and fats: 100 g tahini, 100 g mixed seeds (pumpkin, sunflower, hemp), 1 bag walnuts (100 g), 1 jar almond butter (150 g). Dairy alternatives and extras: 1 litre fortified oat or soy milk, 2 x 400 g tins coconut milk, 1 lemon, 1 lime, fresh ginger (small piece), low-sodium soy sauce, nutritional yeast (if available — adds B12, protein and a cheesy flavour). UK cost: approximately £30–£38. US cost: approximately $36–$44. Most of these items are now widely available at mainstream supermarkets.

This session runs approximately 85–95 minutes. Minutes 0–5: Preheat oven to 200 C / 400 F. Drain and press the tofu between paper towels under a heavy pan for at least 20 minutes (start this first). Begin rinsing quinoa and the green lentils. Minutes 5–15: Start the brown rice in a large saucepan. In a second saucepan, bring the green lentils to the boil with water, a bay leaf and a garlic clove. In a third pan (or the same one after rice is done), cook the quinoa. Minutes 15–30: Cube the pressed tofu into 2 cm pieces, toss with soy sauce, a tablespoon of olive or vegetable oil, smoked paprika and garlic powder. Spread on a lined baking tray and put in the oven. Dice the courgettes and bell peppers, toss in oil and mixed herbs on a second tray and add to the oven. Minutes 30–50: Drain the chickpeas, toss with cumin, a pinch of cayenne and olive oil, spread on a third baking tray (use one of the vegetable trays when the veg is done at 35 minutes) and bake for a further 15–20 minutes until crispy. Meanwhile, make the red lentil dal: saute the diced onion and ginger in a pan for 5 minutes, add cumin and turmeric, add dry red lentils and both tins of coconut milk, simmer for 20 minutes. Minutes 50–65: Prepare overnight oats: five jars, 75 g oats each, 200 ml fortified oat milk, 1 tablespoon almond butter, a handful of mixed seeds, frozen berries. Into the fridge. Drain the green lentils and toss with tahini, lemon juice, a minced garlic clove, salt and pepper — this is your tahini lentil salad. Minutes 65–85: Portion meals: five containers of dal plus rice. Five containers of quinoa plus roasted veg plus baked tofu. Portion the tahini lentil salad across three lunch containers with a handful of kale each. Store the crispy chickpeas in a jar at room temperature.

Monday — Breakfast: overnight oats with almond butter, mixed seeds and frozen berries (approx. 440 kcal, 14 g protein, 62 g carbs, 16 g fat). Lunch: tahini lentil salad with kale and a handful of crispy chickpeas (approx. 450 kcal, 22 g protein, 48 g carbs, 18 g fat). Dinner: red lentil dal with brown rice (approx. 490 kcal, 20 g protein, 78 g carbs, 14 g fat). Snack: a banana with a tablespoon of almond butter (approx. 210 kcal, 5 g protein). Daily total: approx. 1,590 kcal, 61 g protein. Adding a 200 ml glass of fortified soy milk adds 7 g protein and reaches 1,650 kcal. Tuesday — Breakfast: overnight oats (440 kcal). Lunch: quinoa bowl with baked tofu, roasted peppers and courgette, drizzled with tahini and lemon (approx. 510 kcal, 28 g protein, 54 g carbs, 20 g fat). Dinner: dal with rice (490 kcal). Daily protein: approximately 72 g — adequate for a plant-based adult at moderate activity. Wednesday — Breakfast: smoothie made with 200 ml fortified oat milk, frozen berries, a banana, a tablespoon of hemp seeds and a tablespoon of almond butter (approx. 390 kcal, 12 g protein). Lunch: tahini lentil salad with kale (450 kcal, 22 g protein). Dinner: quinoa bowl with baked tofu and roasted veg (510 kcal). Snack: a handful of walnuts (190 kcal, 5 g protein).

Thursday — Breakfast: overnight oats (440 kcal). Lunch: cannellini bean and kale soup — this takes 15 minutes fresh: saute garlic and onion, add drained cannellini beans, the remaining kale or frozen kale, vegetable stock and lemon juice. Serve with a small piece of crusty bread if budget allows (approx. 380 kcal, 20 g protein). Dinner: the final dal container — by now the flavours are particularly deep and rich (490 kcal). Friday — Breakfast: avocado on toast (add one avocado to your shopping for approximately £0.70 / $1.00 extra) with a side of edamame (approx. 420 kcal, 14 g protein). Lunch: final quinoa tofu bowl (510 kcal). Dinner: stir-fried brown rice with frozen edamame, frozen broccoli, soy sauce, ginger and garlic — cook fresh from prepped rice in 10 minutes (approx. 460 kcal, 22 g protein). Weekend: Saturday — a warming grain salad brunch: remaining quinoa if any, warmed through with roasted chickpeas, walnut halves, a big handful of kale massaged with lemon and tahini. Highly satisfying, nutrient-dense and zero cooking required. Sunday — morning: cook a large pot of porridge (80 g oats, 300 ml fortified oat milk, fruit, seeds) before the next prep session. This ensures continuity and feeds you during the prep itself.

Plant-based prepped meals are generally more forgiving in terms of storage than animal-protein meals, with a few important exceptions. Cooked tofu: 4 days in the fridge in an airtight container. Do not freeze baked tofu — it becomes spongy and unpleasant. Cooked lentils and dal: 4–5 days in the fridge; freezes excellently for up to 3 months. Cooked quinoa and brown rice: 4 days in the fridge; freeze well for up to 2 months. Roasted vegetables: 4 days. Crispy chickpeas: 3 days at room temperature in a jar — do not refrigerate as they will soften. Tahini lentil salad: 3–4 days (the tahini dressing firms up in the cold — this is normal, just let it come to room temperature or add a squeeze of lemon to loosen). Overnight oats: 5 days. Reheating: the red lentil dal thickens considerably in the fridge — always add 2–3 tablespoons of water before microwaving and stir halfway through. Rice and quinoa should be microwaved covered with a splash of water added. Baked tofu is good either cold (it has a pleasant chewy texture) or briefly reheated in a dry pan for 2–3 minutes to restore some crispness. Roasted vegetables can be eaten at room temperature over salads, which saves reheating time entirely.

Scaling for two people: approximately double the quantities, increasing the budget to £56–£70 / $68–$84 per week. The prep session extends by about 20–25 minutes, primarily for additional portioning and the larger volume of grains to cook. Protein boosting for athletes: plant-based athletes targeting 130 g+ protein per day need to be more deliberate. Increase tofu to 800 g, add 200 g tempeh (marinate and bake alongside the tofu), and increase edamame to a full 500 g as a daily snack. Nutritional yeast (25–30 g per day) provides an additional 14–16 g of complete protein alongside B12. Pea protein powder dissolved in fortified milk can bridge remaining gaps without compromising the whole-food focus of the diet. Swaps for allergies and preferences: for those avoiding soy (eliminating both tofu and edamame), replace with 400 g marinated and baked jackfruit for the savoury component and increase chickpea, cannellini bean and lentil quantities. For those who find the coconut milk calorie-dense, replace with vegetable stock in the dal — the dish will be lighter but less creamy. For nut allergies, replace almond butter with sunflower seed butter (same texture and cost profile, free from tree nut allergens). Adding fermented foods: a spoonful of kimchi or sauerkraut alongside the dal or quinoa bowl adds probiotics and umami without altering the prep system.
