What is ratatouille?
Other than completely fun to say (rat-tat-TOO-ee) and a super cute movie, ratatouille is wonderful all on its own. Hailing from the Provence region of France, ratatouille is a rustic vegetable dish made of eggplant, zucchini, tomatoes, peppers, and summer squash, stewed together with garlic, onion, and herbs. in other words, the taste of summer in one recipe.
Traditional ratatouille recipes differ depending on the cook; some use thinly sliced veggies layered carefully in a shallow baking dish, while other recipes mix the ratatouille ingredients together in a pot, every which way. Every version is phenomenal.
For this recipe, the vegetables are chopped up and scattered all around the pork loin. They’ll roast and sweeten as they cook down at the higher temperature. By the time the roast is done, all the flavors have mingled together into one amazing dinner.
How to make Pork Loin with Ratatouille:
- First, make your pork loin spice rub. Gather together black pepper, garlic powder, and dried oregano. Blend everything together and rub it all over that beautiful pork loin. Preheat the oven to 400 degrees.
- Next, place the spiced pork loin in an oiled roasting pan that’s large enough to hold all the vegetables. Scatter all the vegetables around the pork roast, then add the basil, garlic, and season everything with salt and pepper. Finally, sprinkle on the capers and the brine. Then pop the roasting pan into the oven and cook for about 1 ½ hours.
- Once or twice, as the pork cooks, turn the vegetables in the pan so they cook evenly and release their juices. The pork is done when it reads 155-160 degrees with a meat thermometer. It should be pink in the center; you don’t want dry pork.
- Remove the pork from the pan onto a carving board, and then tent the roast with foil for a few minutes to let the meat rest before carving. When you’re ready to eat, arrange slices of roasted pork on a platter and surround with the gorgeous summer ratatouille.
Some thoughts on the vegetables:
- Did you forget to peel the eggplant? Don’t worry about it. This is rustic. It’s okay.
- Tomatoes not quite ripe? Use a few canned whole tomatoes instead; cut them up into chunks.
- Did yellow squash look better than the zucchini? Use them instead. They’ll be great.
- Love extra peppers? Throw them in. The more the merrier.
- Hate capers? Go ahead and leave them out. This is your ratatouille!
What kind of eggplant should I buy for ratatouille?
If you’re relatively new to cooking eggplant, here’s how find the right one.
Baby Globe eggplants are generally 3 to 5 inches long, and look just like their larger relative, the American Globe eggplant. The baby variety has a thinner skin than the mature eggplant–and may be less bitter. If you can’t find it, look for slender dark purple Asian eggplant or the slender pale lavender variety, the Chinese eggplant.
If all you can find is one variety of eggplant, the American Globe, or the Italian eggplant, buy it. The recipe will still work wonderfully.
Can I make this dish even if I hate eggplant?
You can. Switch out button mushrooms for the eggplant. It will still be delicious.
What’s the difference between pork loin and pork tenderloin?
It’s easy to whiz through a recipe for pork and think that pork loin and pork tenderloin are the same.
Both are relatively lean cuts of boneless pork, but there are some notable differences. Pork tenderloin, sold whole, is smaller, thinner, and cooks quickly. It would be terribly overdone in this recipe! Save it for the grill.
Pork loin is a bigger cut, more of a roast. Pork loin can go by other names, too. It’s also known as center-cut pork loin roast, center-cut pork roast, pork center loin roast, pork center cut rib roast, pork loin center cut, pork loin center rib roast, pork loin roast center cut, or pork loin rib half. Whew, that’s a lot of names. It helps to memorize a couple and go into your butcher prepared.
Can you make pork loin in a slow cooker?
Yes, you can, but this recipe takes advantage of a relatively short cooking time with higher heat to really caramelize the vegetables. This recipe probably won’t turn out the same if you use a slow cooker or crockpot, unfortunately.

Pork Loin with Ratatouille
- ½ teaspoon dried oregano
- ½ teaspoon garlic powder
- ⅛ teaspoon black pepper freshly ground

- 1 yellow onion cut into chunks
- 3 cloves garlic minced
- 2 teaspoons minced fresh basil (or 1 teaspoon dried)

- 2 tablespoons capers including brine
- Preheat oven to 400 degrees. To make the spice rub, combine the oregano, garlic powder, and pepper in a small bowl.
- Pat the pork dry with paper towels and rub all over with the spice rub. Place the pork in an oiled heavy roasting pan just large enough to hold it comfortably.

- Roast the pork until it is cooked through but still slightly pink in the center, about 1 ½ hours. An instant-read thermometer inserted into the pork should read 155-160 degrees. Turn the vegetables twice during roasting.
