Low Carb Pastelón (Puerto Rican Plantain “Lasagna”)

Pastelón is a Puerto Rican casserole style lasagna with plantains! Plantains are higher in carbohydrates, so for our Low Carb Pastelón we use half the amount plantains and substitute with sliced zucchini. This is the perfect meal for a Sunday family dinner and even makes great leftovers. Although this isn’t a keto recipe, low carb recipes are a great way to indulge in our favorite recipes without going completely off plan. Low carb meals are also great if you’re carb cycling or are slowly starting off with a low carb diet. 


Plantains look similar to bananas but they are more like a vegetable. They are strachier and are a great replacement for potatoes. Plantains are a great source of potassium, which is great when you’re transitioning to a keto or low carb diet. However, just keep in mind that plantains are still high in carbs. Infact 1 plantain is about 53 grams of net carbs. 

Not to worry though! For this entire casserole we only use 2 plantains. While this doesn’t make the dish keto, it is still relatively low in carbs. For the Pastelón, look for ripe plantains with a few black spots. 


Zucchinis are commonly used in low carb lasagna recipes. They are a great alternative because they hold up the casserole and have a mild flavor. Zucchini’s hold a lot of moisture, so we always recommend baking the zucchini slices prior to assembling the “lasagna”. These are great for a low carb diet because they are only 2 net carbs per 100 grams. They are also a great source for Vitamin A and Vitamin C. 


Sofrito is a cooking base made of culantro (not a typo!), onions, garlic and peppers. The mixture is blended together with a food processor or blender. Culantro can be found at most Hispanic grocery stores. 

Here in Canada, it is very hard to find culantro. So for our sofrito I I use a blend of cilantro and parsley. Not authentic, but the flavor is great! You can also add capers or olives to your sofrito. 

Make a big batch of sofrito to use in the pastelón and freeze the remainder. Tip! Freeze them into ice cube trays to have portioned serving sizes. 


The Cheese Debate   

Everyone’s pastelón is different. Some people swear that the authentic version doesn’t have cheese, while some people cannot eat pastelón without it!  We personally love the cheese. We use mozzarella, but feel free to use cheddar or monterey jack. 

What is Adobo Seasoning? 

Adobo seasoning is used in a lot of Puerto Rican/Hispanic dishes. It is a mix of dried garlic, oregano, black pepper and turmeric. You can find this online or at Latin markets.


For our Low Carb Pastelón, we first layer the cooked and dried zucchini slices in a casserole dish. Then we top it with half of the cooked beef mixture, followed with half of the scrambled egg and half of the cheese. We then layer the fried plantain slices, the remaining beef mixture, scrambled egg and final layer of cheese. I believe that our version has less layers than the original, but this helps us lower the carb content for our Low Carb Pastelón.

  • 1 Red Pepper
  • 1 Green Pepper
  • 1 Tsp Dried Oregano

  • Preheat oven to 400°F; then reduce to 350°F (after zucchini is cooked).

  • Place the sliced zucchini on a lined baking sheet, brush with 1 tbsp of olive oil and season with salt and pepper.
  • Bake the sliced zucchini in a preheated oven for 20 minutes.
  • Once the zucchini is done cooking, transfer to a paper towel to remove the excess moisture. Reduce the oven temperature to 350°F.
  • Meanwhile, prepare the filling.
  • Heat 2 tbsp of canola oil in a large pan over medium-high heat. Add 2-4 tablespoons of the sofrito (to taste) and cook for 1-2 minutes until fragrant.
  • Add the ground beef and cook until lightly browned. Add adobo seasoning and continue to cook until fully browned.
  • Add dissolved bouillon cube to the beef and combine.

  • Meanwhile, prepare the plantains.
  • Heat 1/3 cup of canola oil in pan over medium-high heat.
  • Peel the plantains and slice lengthwise. You should get about 3-4 slices per plantain.
  • Once the oil is hot, fry the plantains in batches until both sides are golden brown.
  • Transfer to a paper towel.
  • Assemble the Pastelón
  • Layer the cooked zucchini on the bottom of the baking dish.
  • Top with half of the meat mixture and then half of the whisked egg mixture.
  • Add half of the grated cheese.
  • Assemble the fried plantains on top of the mixture.
  • Finish off the Pastelón with the remaining ground beef mixture and whisked egg (final layer of mozzarella will be added later).
