How to make Creamy Mexican Street Corn Casserole

- Combine corn, seasonings, cheese, mayonnaise, and sour cream in a bowl.

Prep time: 15 minutes | Bake time: 25–30 minutes | Makes: about 6–8 servings
Ingredients
Gather these items
- 4 cups sweet corn kernels (fresh off the cob, or thawed frozen, or two 15-oz cans drained)
- Note: Roasted fresh corn adds the best flavor.
- 1 cup mayonnaise (use full-fat for richest flavor; vegan mayo works for a vegan swap)
- 1 cup sour cream (or plain Greek yogurt for tang and protein)
- 1½ cups shredded Monterey Jack or mild cheddar cheese, divided
- ½ cup crumbled cotija or queso fresco (optional, for finishing)
- 2 tbsp lime juice (about 1 lime)
- 1 tsp chili powder (or smoked paprika for softer smoke)
- 1 tsp ground cumin
- ½ tsp garlic powder
- ½–1 tsp kosher salt, plus more to taste
- ¼ tsp freshly ground black pepper
- 2 green onions, thinly sliced (for garnish)
- ¼ cup chopped fresh cilantro (for garnish)
Optional (for a firmer set): 2 large eggs, lightly beaten
Substitutions: use dairy-free mayo + plant-based sour cream and vegan shredded cheese to make it vegan. For lower fat, swap some mayo for Greek yogurt.
Directions
Follow these short, clear steps
- Preheat the oven to 375°F (190°C). Grease a 9×9-inch (or similar) casserole dish.
- Place the corn in a large mixing bowl. If using fresh corn, scrape kernels from the cob; if canned, drain well.
- Add mayonnaise, sour cream, lime juice, chili powder, cumin, garlic powder, salt, and pepper. Stir until evenly coated.
- Fold in 1 cup of the shredded cheese. If you want a firmer, sliceable casserole, stir in the beaten eggs now.
- Taste and adjust seasoning. Add a little more lime or salt if needed.
- Spoon the mixture into the prepared dish and smooth the top. Sprinkle the remaining ½ cup cheese over the surface.
- Bake uncovered for 25–30 minutes, until the center is hot and the top is bubbly and lightly browned.
- Remove from the oven and let rest 5–10 minutes. This helps the casserole set.
- Garnish with sliced green onions, crumbled cotija, chopped cilantro, and a squeeze of lime. Serve warm.
Quick timing tip: if the top browns too fast, loosely cover with foil for the last 5–10 minutes of baking.
How to serve Creamy Mexican Street Corn Casserole
Best ways to enjoy it
- As a side: pair with grilled chicken, carne asada, or roasted pork.
- For casual gatherings: serve with tortilla chips as a scoopable dip.
- As a main: spoon over rice or mix with cooked quinoa and a green salad.
- For tacos: use it as a filling with shredded lettuce and extra cotija.
- Plating: spoon into shallow bowls, add a sprinkle of cilantro, a lime wedge, and more cotija for color and brightness.
How to store
Storage and reheating tips
- Refrigerate: Cool to room temperature, then store in an airtight container in the refrigerator for up to 3–4 days. Refrigerate within 2 hours of baking.
- Freeze: Wrap the cooled casserole tightly or transfer to a freezer-safe container. Freeze up to 2 months. Thaw in the fridge overnight before reheating.
- Reheat: Oven: 350°F (175°C) for 15–20 minutes covered, until heated through. Microwave: heat individual portions 1–2 minutes, stirring halfway. For food safety, reheat until internal temperature reaches 165°F (74°C).
- Safety note: keep the casserole at safe temperatures (<40°F/4°C in fridge) and discard if left out more than 2 hours.
Tips to make
Helpful cooking tips
- Drain well: if using canned corn, pat dry. Excess liquid makes the casserole watery.
- Roast for depth: char fresh corn briefly on a hot skillet or under a broiler for a smoky note.
- Use room-temperature dairy: mayo and sour cream at room temp mix more smoothly.
- Cheese choice: Monterey Jack melts well; a little sharp cheddar adds tang. Cotija is salty and crumbly — use it as a finish, not the melt base.
- Don’t overbake: pull the dish when it’s bubbly and lightly browned. Overbaking can dry it out.
- Add texture: fold in ½ cup panko or crushed tortilla chips for a slight crunch before baking.
- Make ahead: assemble in the pan, cover, and refrigerate up to 24 hours before baking. Add a few extra minutes to the bake time if baking cold.
Variations
Creative twists
- Spicy chorizo: brown 8 oz chorizo, drain, and fold into the mixture for a meaty version.
- Poblano & roasted pepper: add roasted, diced poblano for earthiness.
- Cilantro-lime crema topping: blend sour cream with extra lime and cilantro for a bright drizzle.
- Vegan: swap mayo and sour cream with vegan alternatives and use plant-based shredded cheese.
- Cornbread-style: fold in ½ cup yellow cornmeal and an extra egg for a denser, cake-like casserole.
- Mexican street corn salad: skip the bake and serve chilled as a salad with diced avocado.
FAQs — Your questions answered
Q: Can I use frozen or canned corn?
A: Yes. Thaw and drain frozen corn well, and drain canned corn thoroughly. For best flavor, roast thawed corn briefly in a skillet or broiler before mixing.
Q: Can I make this ahead of time?
A: Yes. You can assemble in the baking dish, cover, and refrigerate up to 24 hours. Bake straight from the fridge — add 5–10 minutes to the bake time. For longer storage, bake first, then freeze.
Q: Is this recipe gluten-free?
A: The basic recipe is naturally gluten-free if you use gluten-free mayonnaise and cheese. If you add panko or other fillers, choose gluten-free versions.
Q: How do I prevent the casserole from being watery?
A: Drain canned corn, thaw and pat frozen corn dry, don’t overuse watery yogurt, and avoid piling too many wet add-ins. Adding a beaten egg or a small amount (¼–½ cup) of shredded, dry corn tortilla or panko can help bind excess moisture.
Q: Can I make this in a skillet or on the grill?
A: Yes. For a skillet version, cook the mixed filling on the stovetop over medium-low heat until thick, then broil briefly to brown the top. On the grill, cover a cast-iron skillet and finish over indirect heat until heated through and bubbly.
