- One-Pot Wonder: Easy prep, minimal cleanup, and maximum flavor.
Ingredients Breakdown
- Eggplant: Choose a firm, shiny eggplant for the best flavor. If it’s on the larger side, sprinkle with salt and let it sit for 15 minutes to reduce bitterness.
- Zucchini and Yellow Squash: Tender and sweet, you can use just one or both for variety.
- Bell Peppers: Go for a mix of red, yellow, or orange for a pop of color and sweetness.
- Crushed Tomatoes: A can of high-quality tomatoes adds the perfect base for those rich, saucy vibes.
- Fresh Herbs: Basil, thyme, and parsley help bring authentic Provençal flavor to the dish.
- Olive Oil & Garlic: The base of any great Mediterranean dish—don’t skimp on the garlic!
Pro Tip: Don’t have fresh herbs? Dried works fine in a pinch—just use about one-third of the amount (they’re more potent!).
Step-by-Step Instructions
-
Prep the veggies: Dice the eggplant, zucchini, squash, and bell peppers into bite-sized pieces. Mince the garlic.
-
Sauté: Set the Instant Pot to “Sauté” mode and drizzle in olive oil. Add the garlic and sauté for 1-2 minutes, until fragrant. Toss in the diced veggies and stir for 3-5 minutes to soften slightly.
-
Add the sauce: Stir in the crushed tomatoes, a pinch of salt, pepper, and your herbs of choice (fresh or dried). Give everything a good mix to coat the veggies in that delicious sauce.
-
Pressure Cook: Close the lid and set the Instant Pot to “Manual” or “Pressure Cook” mode for 6 minutes. Once done, quick-release the pressure carefully.
-
Final touch: Open the lid and give everything a good stir. Taste and adjust seasoning with more salt, pepper, or fresh herbs as needed.

Chef’s Tips and Tricks

- Make It Ahead: This ratatouille tastes even better the next day, so feel free to make it ahead of time for easy meal prep.
