Quick Picks
In a hurry? Start with these three sensible picks for most UK homes.
- Freezer-safe meal prep containers — a stack you actually like using; the habit sticks when the kit is right
- Freezer labels (easy peel) — label by day and you’ll stop guessing mid-week
- A solid ladle — sounds boring, but it’s the difference between calm portioning and sauce everywhere
Sunday batch cooking has been my anchor for a calm week for as long as I can remember. I started doing it properly when the allotment really got going — there’d be gluts of courgettes, armfuls of tomatoes, bags of root veg that needed using — and I needed a system. One big slow-cooker base that sorts three weeknight dinners turned out to be it. Not three identical reheats. Three meals that feel considered, even when you knocked them together in ten minutes on a Tuesday night.
This Sunday batch cook is my favourite kind of calm: one slow-cooker base that quietly takes care of itself, then turns into three proper weeknight dinners. Not three identical reheats — three meals that feel like you planned ahead (even if you didn’t).
The idea: Make a big, flexible tomato-and-lentil ragu in the slow cooker (add mince if you like). Portion it into “Meal 1 / Meal 2 / Meal 3” tubs. Then finish it three different ways across the week: cosy bowls, stuffed jackets, and a bubbling pasta bake.
- Prep: 15 minutes (chop + dump + stir)
- Cook: LOW 6–8 hours (or HIGH 3–4)
- Portion: 3 tubs for three dinners (+ a freezer bonus if you’ve got extra)
Kit That Earns Its Keep
- Freezer-safe meal prep containers — Get a stack you actually like using. It makes the habit stick.
- Freezer labels (easy peel) — Label by day (“Tue”, “Thu”) and you’ll stop guessing.
- A solid ladle — Sounds boring. It’s the difference between calm portioning and sauce everywhere.
Slow Cooker Tomato & Lentil Weeknight Ragù
One Sunday cook-up that sorts three weeknight dinners. Make it on LOW while you do other things. Portion into tubs, label by day, finish three different ways across the week.
Ingredients
- Onions, finely chopped2
- Carrots, diced small2
- Celery sticks, diced (optional)2
- Garlic cloves, crushed3–4
- Tomato purée2 tbsp
- Chopped tomatoes2 × 400g tins
- Vegetable or chicken stock700 ml
- Red lentils, rinsed250 g
- Smoked paprika1 tsp
- Dried oregano1 tsp
- Balsamic vinegar1 tbsp
- Salt and black pepper
Method
- Build the base: add onion, carrot, celery, garlic, tomato purée, tomatoes, stock, lentils, paprika, oregano, salt and pepper to the slow cooker. Stir to combine.
- Cook: LOW 6–8 hours or HIGH 3–4 hours until lentils are tender and the sauce is thick.
- Finish: stir in balsamic vinegar. Taste and adjust seasoning. Add a splash of water if the consistency has tightened.
- Portion: cool slightly, then divide into labelled tubs — Meal 1 (cosy bowls), Meal 2 (stuffed jackets), Meal 3 (pasta bake). Fridge up to 3 days; freeze up to 3 months.
The one-pot base: Slow Cooker Tomato & Lentil Weeknight Ragù
Makes: 6–8 portions (depending on appetites)
Prep: 15 minutes
Cook: 6–8 hours on LOW or 3–4 hours on HIGH
Ingredients
- 2 onions, finely chopped
- 2 carrots, diced small
- 2 sticks celery (optional), diced
- 3–4 cloves garlic, crushed
- 2 tbsp tomato purée
- 2 × 400g tins chopped tomatoes
- 700ml vegetable stock (or chicken stock)
- 250g red lentils, rinsed
- 1 tsp smoked paprika
- 1 tsp dried oregano
- 1 tsp salt to start (adjust later) + black pepper
- 1 tbsp balsamic vinegar (or a pinch of sugar)
- Optional depth: 1 tbsp soy sauce or Worcestershire-style sauce
- Optional meat version: 500g beef mince, browned first
Method (slow cooker)
- Build the base: Add onion, carrot, celery (if using), garlic, tomato purée, tomatoes, stock, lentils, paprika, oregano, salt and pepper to the slow cooker.
- If using mince: Brown it in a pan first (better texture + flavour), then add to the pot.
- Cook: LOW 6–8 hours or HIGH 3–4 hours, until lentils are tender and the sauce is thick.
- Finish: Stir in balsamic (and soy/Worcestershire-style sauce if using). Taste and adjust salt/pepper. Loosen with a splash of hot water if needed.
Why this works: the base is intentionally flexible — neutral enough to become three different dinners with tiny finishing touches. I’ve made variations of this every few weeks for years. When I’ve got a courgette glut on the allotment, in they go. When the tomato tins are running low, I lean heavier on lentils. The flavour is always there; it’s the finishing that changes the whole feeling of the meal.
Portion it like a peaceful person
Let the ragù cool slightly (so you’re not steaming up the fridge), then portion into tubs:
- Meal 1 tub: 2 portions
- Meal 2 tub: 2 portions
- Meal 3 tub: 2–4 portions (depending on bake size)
- Freezer bonus tub: anything left
Label each tub with the day you plan to eat it. It sounds daft. It’s quietly life-changing. I started labelling by day rather than just date after one too many “is this Tuesday’s or last Sunday’s?” moments — now it’s automatic, takes five seconds, and Monday dinner is genuinely easier.
Three dinners from one cook-up
Meal 1: Cosy bowls (ragù + rice or mash)
Weeknight effort: 10–15 minutes.
Reheat your Meal 1 tub gently until piping hot. Serve over rice, mash, or buttered pasta. Add one “nice” thing: a handful of spinach stirred through, grated cheese, or a dollop of yoghurt.
- Best for: Monday energy
- Make it feel new: chilli flakes + lemon zest, or herbs + olive oil
Meal 2: Stuffed jacket potatoes (ragù + cheese + greens)
Weeknight effort: mostly oven time.
Bake jacket potatoes (or microwave then crisp). Heat your Meal 2 tub. Split, add butter, spoon over ragù, top with cheese, and return to the oven until bubbling. Serve with salad or steamed greens.
- Best for: a “proper dinner” midweek
- Make it feel new: sweetcorn, spring onion, or pickled jalapeños
This one is my personal favourite of the three. There’s something deeply satisfying about a proper stuffed jacket midweek — it feels like you’ve made an effort, even when you haven’t. Jacket potatoes from our allotment plot taste noticeably different to anything from a supermarket bag; earthier, slightly nuttier. Worth growing a row if you have the space.
Meal 3: Cheesy pasta bake (ragù + pasta + creamy shortcut)
Weeknight effort: 20 minutes prep + oven.
Cook pasta to just under al dente. Mix with your Meal 3 tub, tip into a baking dish, top with cheese (and breadcrumbs if you like), then bake until golden and bubbling. Cosy upgrade: stir in 2–3 spoonfuls of crème fraîche or soft cheese before baking for a silky finish.
- Best for: Thursday fatigue / Friday relief
- Make it feel new: add peppers, mushrooms, or leftover roast veg
A simple week plan (so you actually use the tubs)
| Day | Dinner | Extra “nice” thing |
|---|---|---|
| Mon | Cosy bowls | Spinach + grated cheese |
| Wed | Stuffed jackets | Salad + spring onion |
| Fri | Pasta bake | Breadcrumb topping + side greens |
Storage, freezing, and the boring-but-important bits
- Cool quickly: portion into shallow tubs so it cools faster before refrigerating.
- Fridge: use within 2–3 days.
- Freezer: freeze up to 3 months. Defrost overnight in the fridge.
- Reheat: reheat until piping hot all the way through.
A note on red lentils: They thicken considerably as they cool and again when reheated. Add a splash of water or stock when reheating if the consistency has tightened up — it comes back together quickly. I’ve found this particularly noticeable when reheating from frozen: a little extra liquid and a gentle stir and it’s back to the right texture.
Make it yours (easy swaps)
- More veg: courgette, peppers, mushrooms, or frozen mixed veg
- More protein: stir through cooked chicken at the end, or use browned mince
- Different vibe: cumin + chilli + sweetcorn = chilli night energy
- Gluten-free: serve with rice/mash and use GF pasta for the bake
The honest verdict
This is the batch cook I come back to most often — probably once a fortnight through autumn and winter. It’s genuinely flexible, the base is cheap to make, and the three finishing methods mean it never feels like you’re eating the same thing twice. The slow cooker does the hard work on Sunday morning while you’re doing other things — I usually put it on before heading to the allotment and come back to a kitchen that smells like dinner is sorted for the week.
