How to Make James Martin Saturday Morning Lasagne
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the lasagne cooks evenly and browns nicely on top.
- Start the meat sauce: Heat the olive oil in a large pan over medium heat. Add the onion, garlic, carrot, and celery, then cook for 5 to 7 minutes until soft and fragrant.
- Brown the beef: Add the beef mince and cook until browned, breaking it up with a spoon so there are no large lumps.
- Build the flavour: Stir in the tomato purée and cook for 1 minute. Add the chopped tomatoes, beef stock, oregano, thyme, salt, and pepper. Simmer gently for 25 to 30 minutes until thick and rich.
- Make the béchamel: Melt the butter in a saucepan over low heat. Stir in the flour and cook for 1 minute. Gradually whisk in the milk until smooth, then cook until thickened. Stir in the Cheddar, nutmeg, salt, and white pepper.
- Assemble the lasagne: Spoon a layer of meat sauce into the base of a baking dish. Add lasagne sheets, followed by béchamel. Repeat the layers, finishing with béchamel on top.
- Add the topping: Sprinkle the Parmesan evenly over the top to create a golden crust.
- Bake: Bake for 40 to 45 minutes until bubbling and golden. If the top browns too quickly, cover loosely with foil.
- Rest and serve: Remove from the oven and let the lasagne rest for 10 minutes before slicing. This helps the layers hold together.
Tips for Perfect Lasagne
Why is my lasagne watery?
This usually happens if the meat sauce is too thin. Simmer it until thick and rich before assembling.
How do I stop the top from burning?
Cover loosely with foil if the cheese browns too quickly, then uncover for the final 10 minutes.
Should I pre-cook the lasagne sheets?
Most dried lasagne sheets soften perfectly during baking. Make sure the sauces fully cover them.
Can I make this ahead of time?
Yes, assemble the lasagne, cover, and refrigerate for up to 24 hours before baking.
Serving Suggestions
- Serve with a crisp green salad and vinaigrette
- Add garlic bread or focaccia on the side
- Pair with lightly steamed green beans or broccoli

FAQs
Can I bake this as a loaf instead?
This recipe works best in a wide baking dish so the layers cook evenly. A loaf tin would be too deep and may not bake through properly.
What size dish works best for lasagne?
A dish around 23 x 30cm is ideal for even layers and consistent baking.
Can I use fresh pasta sheets?
Yes, fresh pasta works very well and gives a softer texture. Reduce the baking time slightly if using fresh sheets.
Is this lasagne suitable for children?
Yes, the flavours are rich but not spicy, making it family friendly.
