1. Which ingredients can be replaced in this vegan ratatouille recipe?

This dish is so versatile and allows you to experiment with so many veggies. Feel free to add or replace the vegetables in the recipe with any of your favorites like:

  • Broccoli
  • Cauliflower
  • Summer squash
  • Butternut squash
  • Potatoes (it’s best to boil them first because they take a bit longer to cook)
  • Brussels sprouts
  • Mushrooms

You can replace the plum tomatoes with diced tomatoes or even with marinara or pizza sauce if you like.

For a healthy vegan protein addition, stir in a can of rinsed and drained chickpeas or another favorite bean. Add the beans when you stir everything together and cook according to the recipe instructions to allow the flavors to meld.

If you’re not vegan or vegetarian, then you can add shredded parmesan, goat cheese, or pecorino on top. It brings some great cheesy flavors to the dish.

2. How to make ratatouille with chicken?

I love the addition of chicken to ratatouille. It turns this easy recipe into a full meal that’s even more satisfying and filling. For chicken ratatouille, use boneless skinless chicken thighs or breasts and cut them into 1-inch pieces.

Start the recipe by searing the chicken until golden, and set aside on a plate. Then follow the recipe as written and return the seared chicken to the pot with the fried veggies.

3. How to make this easy ratatouille recipe with other protein

You could also add turkey or beef just as you would add the chicken.

In fact, if you have leftover cooked turkey or chicken, ratatouille is a great way to transform it into a new meal. Shred or chop the meat and add it to the pot with the fried veggies. There’s no need to sear the meat since it’s already cooked.

Last but not least, my favorite protein addition to this easy ratatouille recipe is shrimp or fish. It transforms the dish into an amazing Mediterranean pot! Use raw peeled and deveined shrimp or fish fillet chunks. Simply add them when the ratatouille has about 10-12 minutes left to cook. Seafood cooks very quickly when added to the simmering sauce.

4. How to cook it in the oven

Wondering how to make baked ratatouille?

Simply follow the recipe as written. When you get to the point where you’re making the sauce, preheat the oven to 350°F (180°C). Once you add all the fried veggies to the pot, transfer the dish to the preheated oven and bake uncovered for 30-35 minutes. Stir a few times to ensure even cooking. This is a great hands-off way to finish the ratatouille so you can move on to other things.

5. How to make ratatouille in an Instant Pot?

For an extra time-saver, you can always turn to your pressure cooker to whip this recipe up in minutes.

How to make ratatouille in the Instant Pot*:

  1. Press the SAUTE option on the Instant Pot and set it for 15 minutes, then add in half of the oil.  
  2. Sauté the veggies just as you would in the pan. You need to cook them in batches to avoid overcrowding the pot, so make sure you adjust and divide the oil accordingly.
  3. Once all the veggies are partially fried, start making the tomato sauce. Add the onion, garlic, and thyme to the Instant Pot and sauté for about 3 minutes. Add the plum tomatoes with their juices and the balsamic vinegar. Break the tomatoes with the back of a wooden spoon to create a thick sauce. Season with salt and pepper. Stir in the fried veggies, cherry tomatoes, and basil.
  4. Secure the lid on and set to cook at HIGH PRESSURE for 2 minutes. When the timer is up, quickly release the pressure manually and carefully remove the lid.

6. How to make this vegan ratatouille with pasta?

Pasta works so great with ratatouille! Cook the pasta separately according to package instructions. Once cooked, reserve about 1/4-1/3 cup of the pasta water and drain the noodles.

When the ratatouille is done, add the cooked pasta to the pot with the reserved pasta water. Adding the pasta water will make the tomato sauce adhere better to the pasta noodles.

7. How to cut veggies for this recipe

The key to perfectly cooked easy ratatouille is cutting the vegetables evenly.

How you cut them depends on your preferences, however. Some people love the veggies chopped into smaller pieces. Others prefer large chunks. However you like your veggies, just be sure they’re all about the same size and shape.

I’m definitely on team chunky veggies, as you can feel their texture so much better.

If you’re on the other side and like smaller chopped veggies, reduce the cooking time from 30 minutes to about 20 min. It’s good to have a bit of a crunch in each bite, and it’s always best to not overcook your veggies.
