Slow Cooker Lasagne Recipe
Ingredients
Lasagne Filling
500g 5% lean beef mince
1 onion, diced
4 garlic cloves, minced
1 carrot, grated
2 bay leaves
2 tbsp mixed Italian herbs
50ml beef stock
1 x 400g can chopped tomatoes
1 tbsp tomato purée
Salt & pepper, to taste
To Finish
4 dried lasagne sheets
1 packet @Schwartz Cheddar Cheese Sauce

Instructions
-
Add your base ingredients.
Into the slow cooker, add the beef mince, onion, garlic, grated carrot, bay leaves, herbs, stock, chopped tomatoes, tomato purée, and a generous pinch of salt and pepper. -
Cook the ragu.
Stir everything together, then cook on high for 4 hours or low for 8 hours, until the beef is tender and flavours have developed. -
Layer your lasagne.
One hour before serving, break up the lasagne sheets and nestle them into the ragu (no need to pre-cook). Pour over the cheddar cheese sauce and stir lightly to coat. Continue cooking for the final hour. -
Finish with cheese.
Ten minutes before serving, sprinkle mozzarella evenly on top. Pop the slow cooker pot (only if oven proof) under a hot grill for 5 minutes to get that golden, bubbly lasagne crust. -
Serve & enjoy.
Garnish with fresh basil and serve with a crisp side salad or steamed greens for the ultimate high-protein comfort meal.
