Pastel de Choclo is a Chilean baked casserole: spiced ground meat on the bottom, a blended sweet corn topping on top, baked until the corn sets and browns. This version uses ground lamb and black olives, which gives the filling a stronger, more savory flavor than the traditional beef or chicken versions. It takes about 80 minutes start to finish and feeds six people with minimal fuss.
Shopping notes
- Ground lamb: Grass-fed is called for in the recipe and does taste better here — the fat is more flavorful and the filling won’t taste flat. If your store only carries regular ground lamb, it still works fine.
- Sweet corn kernels: Fresh corn cut from the cob gives the smoothest topping, but frozen kernels are a perfectly good substitute. Canned corn is too wet and too salty — skip it.
- Cornmeal: This is a thickener for the topping, not a main ingredient. Standard fine or medium-grind cornmeal from any grocery store works. Polenta meal is the same thing under a different name.
- Smoked paprika: Regular paprika won’t give the same depth. Smoked paprika is now stocked in most supermarkets, usually near the regular spices. Buy it — skip the regular paprika as a swap here.
- Black olives: Pitted olives sold in a jar or can are fine. Kalamata olives also work and add a sharper brine if you prefer that.
Before you start
The one thing that matters most with ground lamb is getting it properly browned before you add the spices. Crowding the pan traps steam and the meat stews gray instead of browning — use a large skillet and break the lamb into small pieces as it cooks. Brown meat has more flavor than gray meat, full stop. The second thing worth knowing: blend the corn topping until it is genuinely smooth. A chunky topping won’t set evenly in the oven and can stay wet in the middle while the edges over-bake. If your blender struggles with the corn, add the milk gradually rather than all at once.
Common problems and fixes
- Corn topping is still liquid after 35 minutes: Your oven may run cool, or the topping was blended too thin. Give it another 10 minutes uncovered. If it’s still wet, loosely tent with foil to stop the top burning and keep baking until the center doesn’t jiggle when you shake the dish.
- Filling is greasy: Ground lamb can release a lot of fat. After browning, tilt the skillet and spoon off the excess fat before adding the spices. Leaving it all in makes the finished dish oily and heavy.
- Topping slides off the filling when serving: The corn layer needs to be fully set before you cut into it. Let the dish rest for 10 minutes out of the oven — cutting it hot causes the topping to slip.
- Filling tastes bland: Ground meat needs salt at the cooking stage, not just at the end. Season the lamb while it’s browning, then taste and adjust again after the spices go in.
- Olives taste too sharp and dominate: Rinse the sliced olives under cold water before adding them. This softens the brine flavor without removing it entirely.
Make-ahead notes
The lamb filling can be cooked up to two days ahead and kept covered in the fridge. The corn topping is best blended fresh on the day you bake — it can separate and turn watery if it sits overnight. Once baked, the whole dish keeps in the fridge for up to three days. Reheat individual portions in a microwave at medium power for 2–3 minutes, or cover the whole dish with foil and warm it in a 160°C (325°F) oven for about 20 minutes. The dish also freezes well after baking: wrap tightly and freeze for up to two months. Thaw overnight in the fridge before reheating — do not reheat from frozen, as the corn topping turns grainy.
Lamb Mince and Olive Pastel de Choclo
Ingredients
Lamb Filling
500 grams ground lamb (minced lamb) - Grass-fed recommended for optimal flavor
1 large onion - finely chopped
3 cloves garlic - minced
1 tablespoon olive oil - extra virgin
1 teaspoon cumin - ground
1 cup black olives - pitted and sliced
1 teaspoon paprika - smoked for added depth
Corn Topping
- 4 cups sweet corn kernels - fresh or frozen
1 cup milk - whole milk for creaminess
2 tablespoons cornmeal
30 grams butter - unsalted
1 teaspoon sugar - optional, for balancing flavors
Instructions
- Preheat the oven to 180°C (350°F).
- In a large skillet over medium heat, warm the olive oil and sauté the onion until translucent, about 5 minutes. Add the garlic and sauté for another minute until aromatic.
- Add the lamb mince to the skillet, breaking it up with a wooden spoon, and cook until browned, approximately 10 minutes.
- Stir in the cumin, smoked paprika, and sliced olives. Season with salt and pepper to taste. Cook for an additional 5 minutes, allowing the spices to meld.
- Meanwhile, in a blender, combine corn kernels, milk, butter, and cornmeal. Blend until smooth. Add sugar, if using, and season with salt and pepper to taste.
- Spread the lamb mixture evenly in a baking dish. Pour the corn mixture over the top, smoothing with a spatula.
- Bake in the preheated oven for 30-35 minutes or until the corn topping is set and slightly golden.

FAQ
How do I know when the ground lamb is fully cooked?
Ground lamb is cooked through when it reaches an internal temperature of 160°F (71°C) and shows no pink. If you don’t have a meat thermometer, break a piece open — fully cooked ground lamb is uniformly brown-gray all the way through, not pink or red in the center.
Can I use a different ground meat instead of lamb?
Yes — ground beef works well and is the most common choice in traditional versions of this dish. Ground chicken or turkey also work, but cook those to 165°F (74°C) and make sure there is no pink remaining before transferring to the baking dish.
Do I need a blender, or can I use a food processor?
A food processor works fine for the corn topping. The goal is a smooth, pourable mixture, so process it longer than you think you need to — about 2 minutes — stopping to scrape down the sides once or twice.
Can I assemble the dish the night before and bake it the next day?
You can assemble it up to a few hours ahead and refrigerate it unbaked, but not overnight — the corn topping absorbs liquid from the filling and the texture suffers. If you want to prep ahead, store the cooked filling and the blended topping separately, then combine and bake on the day.
