The vibrant yellow of the mashed potatoes immediately caught my eye, and the cool, creamy filling promised a welcome respite from the summer heat. One bite, and I was hooked!

Cook Time: 20 minutes
Total Time: 50 minutes
Servings: 4
Dietary Type: Gluten-Free

Ingredients

3 lbs yellow potatoes
1 teaspoon chili powder
1 tablespoon oil
Salt & pepper to taste
10 black olives
1 lb queso fresco or 1 lb farmer cheese, cubed
1 small minced onion
4 lemons
3 hard-boiled eggs
1 (6 ounce) can tuna, drained
1 cup mayonnaise
1 small onion, finely chopped
4 ounces fresh cheese, cubed
1 avocado, peeled and sliced
3 hard-boiled eggs, sliced

Equipment Needed

Large pot
Potato masher or ricer
Mixing bowls
Serving dish or mold

Instructions

First, squeeze the lemons and place the minced onion in a bowl with the lemon juice. Season with salt, pepper, and chili powder. This mixture will marinate the onion and provide a vibrant base for the potatoes.
Next, boil the potatoes with their skins on until they are fork-tender. This usually takes about 20 minutes.
Carefully peel the potatoes while they are still warm. Be cautious as they will be hot!
Now, mash the peeled potatoes using a potato masher or ricer. You want a smooth, lump-free consistency.
Add the lemon juice and onion mixture to the mashed potatoes. This is where the distinctive tangy flavor of Causa comes from.
Gradually add the oil while mixing. This helps to keep the mixture smooth and prevents it from becoming too dry. Continue mixing until the potatoes are well combined and have a slightly glossy appearance. Taste and adjust the seasoning with additional salt and pepper as needed.
If you want to serve the Causa without the tuna stuffing, simply place the potato mixture into a mold or serving dish. Chill for at least 1½ hours to allow it to firm up.
To unmold, carefully invert the dish onto a serving plate. Garnish with olives, quartered hard-boiled eggs, and cubes of cheese before serving.
For the stuffed version (Causa Rellena), divide the causa mixture into three equal parts.
Cover the bottom of your serving dish or mold with one part of the potato mixture. Spread it evenly to create a base layer.
In a separate bowl, mix the drained tuna with mayonnaise and the finely chopped onion. This will be the creamy, savory filling for your Causa.
Add a layer of half the tuna mixture over the potato base. Spread it evenly to cover the entire surface.
Add a second layer of causa (another third of the potato mixture) on top of the tuna. Gently spread it to create an even layer.
Spread the remaining tuna mixture over the second potato layer.
Arrange the sliced avocado evenly over the tuna.
Cover with the final layer of causa (the last third of the potato mixture). Gently spread it to create a smooth, even top layer.
Finally, garnish with hard-boiled egg slices, cheese cubes, and olives. Get creative with your presentation!
Refrigerate for at least 1½ hours to allow the Causa Rellena to set and the flavors to meld. This step is crucial for achieving the desired texture.

Expert Tips & Tricks

Use a potato ricer for the smoothest mashed potato texture.
Don’t overwork the mashed potatoes, as this can make them gluey.
If the potato mixture is too dry, add a little more lemon juice or oil. If it’s too wet, add a little more mashed potato.
For a spicier kick, add aji amarillo paste to the potato mixture or the tuna filling.
Make the potato mixture a day ahead of time and store it in the refrigerator to save time on the day of serving.
If you don’t have a mold, you can assemble the Causa Rellena directly on a serving platter.

Serving & Storage Suggestions

Serve Causa Rellena cold as an appetizer, side dish, or light meal. It’s perfect for picnics, potlucks, or summer gatherings. To serve, slice the Causa into wedges and present on a platter. Garnish with extra olives, egg slices, and a sprig of parsley or cilantro for visual appeal.

Leftover Causa Rellena should be stored in an airtight container in the refrigerator. It will keep for up to 3 days. Unfortunately, due to the mayonnaise and avocado, it is not recommended to freeze Causa Rellena.

FAQs (Frequently Asked Questions)

Q: Can I make Causa Rellena ahead of time?
A: Absolutely! In fact, it’s recommended. Making it a day ahead allows the flavors to meld and the Causa to set properly.

Q: Can I use a different type of potato?
A: Yellow potatoes are traditionally used for their creamy texture and slightly sweet flavor. However, you can experiment with other types of potatoes, such as Yukon Gold or even red potatoes, depending on your preference.

Q: What can I use if I can’t find queso fresco?
A: Farmer cheese is a great substitute for queso fresco. You can also use mozzarella or any other mild, slightly salty cheese.
