Step-by-Step Instructions
Preparation
- Salt and drain the eggplant: Place cubed eggplant in a colander, sprinkle with salt, and let drain for 30 minutes. This step removes bitterness and excess moisture. Rinse and pat dry before using.

Assembly
- Add all prepped vegetables to the slow cooker.
- In a small bowl, whisk olive oil, tomato paste or sauce, herbs, salt, and pepper. Pour over the vegetables and toss gently to combine.
- Add bay leaf (if using) and cover with the lid.
Slow Cooking
- Cook on LOW for 4 ½ to 7 hours, depending on your slow cooker and vegetable size.
- Alternatively, cook on HIGH for 2 to 5 hours.
- After cooking, uncover and cook an additional 30-60 minutes to allow excess liquid to evaporate and flavors to deepen.
Finish & Serve
- Remove bay leaf, if used.
- Taste, adjust salt, and stir in fresh basil.
- Top with shredded Parmesan cheese (optional) just before serving.
