Prepare the Vegetables:
Wash and dice the eggplant, slice the zucchinis, chop the onion, dice the red and yellow bell peppers, and chop the tomatoes.
Sauté the Onion and Garlic:
In a large pan, heat olive oil over medium heat. Add chopped onions and minced garlic. Sauté until the onions are translucent.
Add Bell Peppers:
Add the diced red and yellow bell peppers to the pan. Cook for 3-4 minutes until they begin to soften.
Add Zucchinis and Eggplant:
Incorporate the diced zucchinis and eggplant into the pan. Cook for an additional 5-7 minutes until the vegetables are slightly browned.
Add Tomatoes and Seasoning:
Stir in the chopped tomatoes, dried thyme, dried oregano, salt, and black pepper. Reduce the heat to low, cover the pan, and let it simmer for 20-25 minutes.
Simmer Until Vegetables are Tender:
Allow the mixture to simmer until all the vegetables are tender but not mushy. Stir occasionally to prevent sticking.
Garnish and Serve:
Once done, remove the pan from heat. Garnish with fresh basil leaves. Serve the Ratatouille warm as a side dish or over cooked pasta or rice.
