cooking tips for making slow cooker ratatouille
Prepare ratatouille in a number of ways. It can be a a simple sauté or a layering of the vegetables in a casserole dish and baking it in the oven. My personal preference is in a slow cooker. I use the slow cooker setting on my Instant Pot. The flavors of the vegetables and spices blend and mellow while cooking without becoming mushy. With a little chopping and measuring, the slow cooker does most of the work for this dish.
- Summer vegetables are the best for making Slow Cooker Ratatouille. But this is a very forgiving recipe and even winter vegetables are fabulous in the dish.
- Cut all the vegetables in the same size pieces. This helps them all cook at an even rate.
- This is a great make ahead dish. Slow Cooker Ratatouille tastes even better on day 2 or even 3!
- Reheat this tasty side dish over medium low heat and stir occasionally. Or heat in the microwave on 70% power for 1 minute. Continue heating at 30 second intervals. Or heat covered in a 350 degree F oven for 15 to 20 minutes.
what to serve with ratatouille
Serve as a side with grilled chicken or fish. Top creamy Parmesan polenta, pasta, or rice with the vegetable medley for a filling, satisfying, and healthy dinner. Any leftovers can become a filling for omelets, tossed with balsamic vinegar and extra virgin olive oil for a cold vegetable salad. Use as a topping on crostini for an appetizer too.
