Ingredients You’ll Need

Here’s what goes into your slow cooker (aka the most reliable member of the household):

6 chicken thighs, boneless, skinless
¼ cup onion, chopped
1 tablespoon olive oil
2 cups sweet pepper, chopped
2 cups eggplant, chopped
2 cups zucchini, chopped
4 cloves garlic, crushed
1 ¾ cup diced tomatoes (1 can)
2 tablespoons tomato paste
1 teaspoon Better than Bouillon chicken base
1 teaspoon salt
½ teaspoon black pepper

how to make Slow Cooker Ratatouille with Chicken

1) Start with the base

Pour the olive oil into the slow cooker. Add the chopped onion and about half of the diced tomatoes. This helps build a flavorful, saucy foundation right away.

2) Layer in the veggies

Add your sweet peppers, eggplant, and zucchini. Spread them out a bit so they cook evenly. (Think: veggie blanket.)

3) Nestle the chicken on top

Place the chicken thighs right on top of the vegetables. You’re basically tucking them in for a long, delicious nap.

4) Mix up the “flavor sauce”

In a bowl, mix together:

garlic
remaining diced tomatoes
tomato paste
Better than Bouillon chicken base
salt, pepper
basil, thyme
onion powder

Stir until it looks like a thick, herby tomato sauce.

5) Pour and cook

Pour the tomato mixture all over the chicken and veggies. Put the lid on.

Cook:

High: 3–4 hours
Low: about 6 hours

Slow cookers can be a little dramatic and vary by model, so if your chicken shreds easily, you’re golden.

6) Shred and let it soak

When it’s done, use two forks to shred the chicken a bit right in the pot. Let it sit for a few minutes so the chicken drinks up some of that saucy goodness.

Want it thicker? Turn it to high and cook uncovered for about 10 minutes to reduce extra liquid.

Serving Ideas (Because We All Get Bored)

Over rice (white, brown, jasmine—whatever you’ve got)
Over quinoa for a protein-y, hearty bowl
With crusty bread to scoop up that sauce (highly recommended)
As-is in a big cozy bowl, eaten standing at the counter… like a true busy adult

Tips for the Best Results

Don’t skip the tomato paste. It adds richness and makes the sauce taste like it’s been simmering forever.
Even chopping = even cooking. If your zucchini is tiny and your eggplant is huge, one turns mushy while the other stays firm.
Eggplant tip: If you’re sensitive to eggplant texture, chop it a little smaller than the other veggies so it gets extra tender.
Sauce too watery? It happens. Just remove the lid for 10 minutes on high and let it thicken up. It’s not “watery,” it’s just “soup-adjacent” and temporarily confused.

FAQs About Slow Cooker Ratatouille with Chicken

Can I use chicken breasts instead of thighs?

Yes! Chicken breasts work, but they can dry out more easily. If you use them, check for doneness a bit earlier and shred gently so they stay juicy.

Can I add more vegetables?

Absolutely. Mushrooms, more peppers, or even a handful of spinach stirred in at the end are great. Just keep the overall volume reasonable so your slow cooker isn’t packed to the brim.

How do I store leftovers?

Let it cool, then store in an airtight container in the fridge for 3–4 days. It reheats well in the microwave or on the stovetop.

Can I freeze Slow Cooker Ratatouille with Chicken?

Yes! Freeze in portions for up to 2–3 months. Thaw overnight in the fridge, then reheat gently. (The zucchini will be softer after freezing, but the flavor stays delicious.)

What if I don’t have Better than Bouillon chicken base?

You can swap in chicken bouillon granules or a crumbled bouillon cube. If you only have broth, use a small splash—but don’t add too much liquid since the veggies release plenty as they cook.
