I can't even begin to tell you how much I love this cuban pork casserole. If you're NOT new here, you're already well-acquainted with my love of casseroles in general. I love that you can make a BIG meal in a single pot, with all the important nutrition boxes checked, and it feeds a crowd. I also love that casseroles tend to taste even better as leftovers and freeze EXCEPTIONALLY well, making them the perfect meal prep option. This cuban pork casserole has my heart because it fills all those needs …but it's also SO DIFFERENT. The flavors are in a league of their own and, if you enjoy food with depth and personality, you will love this dish.

If you're following along on our Cook Once, Eat All Week healthy meal prep series, this casserole couldn't be easier to make after you've prepped your base components (see this post). If you're not following along on that week of meal prep OR if you're just revisiting this post because this casserole was just THAT GOOD and you need to make it again (word), we've got you covered with some from-scratch instructions below.

Either way, this dish is fresh, balanced, and delicious. Plantains are used for starch, red bell peppers for flavor + a veggie boost, and seasoned shredded pork for protein. The whole thing is baked and then topped with a fresh mango salsa for a true flavor explosion. We hope you love this Cuban pork casserole as much as we do!

Insider “get dinner on the table” tip: if you don't want to make your own mango salsa (word, again), I won't tell if you grab that jar of pre-made mango salsa from the grocery store produce section!

  • Author: Cassy
  • Prep Time: 15 minutes
  • Cook Time: 8 hours 30 minutes
  • Total Time: 8 hours 45 minutes
  • Yield: 4-6 1x



For the Pork:

  • 1, 3 pound pork shoulder
  • 1/2 tablespoon coarse sea salt
  • 1 tablespoon dried oregano
  • 1 tablespoon dried parsley
  • 1 teaspoon cumin
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon garlic powder

For the bell peppers:

  • 4 red bell peppers, cut into 1-inch pieces
  • 1 teaspoon extra virgin olive oil
  • 2 tablespoons of lime juice (about one lime)

For the plantains:

  • 1/2 teaspoon coarse sea salt
  • 3 green plantains, diced into 1/2-inch cubes
  • 1 teaspoon extra virgin olive oil

For the Mango Salsa:

  • 3/4 cup mango, medium dice
  • 1 deseeded jalapeno, small dice
  • 1/2 small red onion, finely diced
  • 2 tablespoons lime juice, or juice of one lime
  • 1/4 teaspoon coarse sea salt
  • 1/4 cup chopped fresh parsley


  1. Season pork shoulder with 1/2 tablespoon coarse sea salt. Place in the slow cooker. Cook on low for 8 hours on low, or about 6 hours on high, until pork easily shreds apart. See here for Instant Pot method.
  2. Combine 4 cups shredded pork with remaining seasonings, and taste to see if additional salt is needed.
  3. Preheat oven to 400 F.
  4. Toss bell peppers with one teaspoon olive oil. Spread out onto a sheet pan and roast for 30-40 minutes, until skins are slightly blackened and wrinkled.
  5. Toss cubed plantains with one teaspoon olive oil and 1/2 teaspoon sea salt. Spread out onto a sheet pan and roast for 30-40 minutes, until cubes are slightly browned. These can roast at the same time as the peppers if your oven has room.
  6. Once peppers and plantains have finished roasting, reduce the oven heat to 350 F. Toss the peppers in the lime juice and then spread them in an 8×8 pan, top with the plantains, and then top with the shredded pork. Bake for 30 minutes.
  7.  While the casserole is baking, combine all ingredients for the mango salsa in a medium-sized bowl.
  8. To serve, spoon salsa on top of individual servings of casserole.

    I have shredded pork I made earlier this week. Do you know what quantity you would use if you aren’t making the pork from scratch? 2 cups or 3 cups? Thank you

    1. Cassy says:

      I’d go with 3 cups, but my bias is for bigger dishes 🙂

  2. Clara Crossland says:

    I assume I should peel the red peppers?

  3. Kayleigh says:

    HELP. I have made this twice now and BOTH times I ended up with plantains as hard as rocks and a dry dish overall. The first time I followed the recipe to a T and the red peppers were mushy, rock hard plantains and overcooked pork (from the second bake I imagine). The second time I skipped the first bake of the peppers which was a vast improvement to the end result but the plantains were still a disaster. I covered the casserole dish when I added the pork and cut the bake time down to 20 minutes at 325 instead of 350 and the pork stayed juicy.

    what is going wrong? i want this dish to work!

  4. Jessica says:

    I like a lot of the Cook Once recipes but this a the driest thing my husband and I have ever choked down. So disappointed. I keep checking the recipe to see if I did something wrong, but I followed exactly. Dried out pork, rock hard plantains, and just blah with no sauce or flavor!

  5. Rob says:

    I started this recipe and it looked like it was going to be dry. I cut the plantains down to 1/2” chunks before roasting. That helped with the firmness. Because it looked dry, I mixed all the plantains peppers and pork together, and I had 1 cup of leftover tomatillo green enchilada sauce that I mixed in. I loaded all that into the dish and cooked for 30 minutes at 350. It turned out really well!!!!

      So glad you enjoyed it, Rob! Thanks for your tips!
