Ingredients
Scale
Tomato Sauce and Seasoning
- 4 garlic cloves, 3 crushed, 1 left whole
- 400g can chopped tomatoes
- Bunch oregano, leaves chopped
- Large pinch chilli flakes
- Salt and freshly ground black pepper, to taste
Vegetables and Herbs
- About 300g (11oz) baby or normal aubergines, sliced
- 2 courgettes, sliced
- ½ large jar roasted red peppers
- 3 beef tomatoes, sliced
- Bunch basil, torn (save a few leaves for sprinkling over)
Other Ingredients
- Small baguette, sliced and toasted
- 2 x 125g balls mozzarella, torn
- Green salad, to serve
Instructions
- Prepare the tomato sauce: Set your slow cooker to High or the browning setting and add the 3 crushed garlic cloves, canned chopped tomatoes, half the chopped oregano leaves, chilli flakes, salt, and pepper. Cover and simmer while you prepare the vegetables, allowing the flavors to meld.
- Layer the vegetables and herbs: Remove most of the sauce from the slow cooker, leaving some at the bottom. Begin layering half of the vegetables and herbs with seasoning in the cooker—start with aubergines, courgettes, roasted red peppers, sliced tomatoes, basil leaves, and remaining oregano.
- Add bread and cheese layers: Add half of the toasted baguette slices, which have been rubbed with the whole garlic clove for flavor, followed by half the torn mozzarella and half of the reserved tomato sauce. Press everything down firmly to compact the layers.
- Repeat layering: Repeat with the remaining vegetables, herbs, tomato sauce, bread, and mozzarella, again pressing down well to compress the layers evenly for cooking.
- Cook in the slow cooker: Cover and cook on High for 5 to 6 hours until the vegetables are tender and flavors are well combined.
- Finish under the grill (optional): If your slow cooker pot is grill-safe, place it under the grill briefly just before serving to brown and bubble the top, creating a golden crust. Otherwise, transfer to a baking dish for this step.
- Serve: Top with the reserved torn basil leaves and serve alongside a fresh green salad for a complete meal.
Notes
- Using a garlic clove to rub on the toasted bread adds subtle flavor without overpowering the dish.
- If your slow cooker insert is not grill-safe, transfer the bake to an ovenproof dish to finish under the grill.
- Feel free to adjust the amount of chilli flakes to your preferred spice level or omit for a milder taste.
- Leftover bake can be refrigerated for up to 3 days and reheated gently before serving.
- This dish is naturally vegetarian; to make it vegan, substitute mozzarella with a plant-based cheese alternative.
