A rich beef lasagne built on our onion- and garlic-free stock, garlic-infused oil and just a little tomato paste, layered with a lower-lactose cheese sauce. Have it with pasta, or skip the sheets for soft eggplant layers.
Lasagne felt like a special-occasion food I'd lost — too much onion, garlic and tomato for my pouch to handle without a rough night. This version keeps the deep, layered comfort and gets there a gentler way.
The meat sauce uses garlic-infused oil (all the garlic flavour, none of the FODMAP that comes with the actual clove), a small squeeze of tomato paste instead of a whole tin of tomatoes, and a spoon of miso for savoury depth. Soft carrot and courgette go in for goodness. On top sits the same easy cheese sauce I use for mac and cheese. And the pasta's up to you — proper sheets, or soft eggplant layers for a lighter, moussaka-style version.
Ingredients
- Meat sauce*
- 1 tbsp garlic-infused oil
- 500 g beef mince
- 150 g carrot, peeled and finely diced
- 150 g courgette, finely diced
- 30 g tomato paste
- 15 g miso paste
- 400 ml onion-free stock (or other low-FODMAP stock)
- 1 tsp dried oregano
- 1 /2 tsp dried thyme
- 1 /4 tsp salt
- 1 /4 tsp black pepper
- Cheese sauce*
- 40 g butter
- 40 g plain flour
- 400 ml lactose-free milk
- 200 ml onion-free stock
- 150 g tasty cheese, grated
- 40 g parmesan, finely grated
- 1 /4 tsp ground nutmeg
- Layers & top*
- 250 g lasagne sheets
- 40 g mozzarella, grated
Method
- Heat the garlic-infused oil in a large pan over a medium heat. Add the beef mince and brown it well, breaking it up as it cooks.
- Stir in the diced carrot and courgette and cook for 5 minutes, until starting to soften.
- Add the tomato paste and miso and cook for a minute, then pour in the stock. Add the oregano, thyme, salt and pepper. Simmer gently for 25–30 minutes, until thick and the veg is soft.
- While it simmers, make the cheese sauce: melt the butter, stir in the flour and cook for a minute. Slowly whisk in the lactose-free milk and stock until smooth, then simmer until thickened. Off the heat, stir in the cheddar, parmesan and nutmeg.
- Heat the oven to 180°C. In a baking dish, layer meat sauce, lasagne sheets and cheese sauce, repeating and finishing with cheese sauce. Scatter the mozzarella on top.
- Bake for 35–40 minutes, until bubbling and golden. Rest for 10 minutes before cutting — it holds together far better.
Gentler swaps
Pasta, or no pasta? Plain white lasagne sheets are the gentlest, lowest-residue choice. For a lighter, naturally gluten-free version, skip the sheets and layer with soft roasted eggplant slices instead — moussaka-style — which keeps the pouch score down and adds veg. Wholemeal sheets bring more fibre and nutrition but more roughage, which can loosen output and lifts the score a touch.
Tomato: a small amount of tomato paste gives that rich tomato note with far less acid and FODMAP load than a tin of tomatoes. If your gut is settled and you want it saucier, you could add a few chopped fresh tomatoes.
Stock & garlic: our onion-free, garlic-free stock and garlic-infused oil carry the savoury, garlicky base without the onion and garlic solids that tend to cause wind.
For the family
Cook once — your gentle version, plus how to pep it up for everyone else.
Make the one meat sauce, then split it before it goes in the dish. Your half stays as it is. For the family half, simmer in a tin of chopped tomatoes with a chopped onion and a clove of garlic, maybe a splash of red wine — then layer, top with extra tasty cheese, and bake. Same lasagne out of the oven; yours is simply the gentle one. A little chilli or fresh basil on their plates finishes it off.
