This shrimp and avocado casserole is my answer to quick craving-crushing dinners that feel festive without being fussy. The natural sweetness of tender shrimp meets cool chunks of avocado and the crunch of tortilla chips for a perfect forkful every time. A creamy, melty cheese topping brings it all together into something that wows at weeknight tables and casual get-togethers alike.
I first whipped up a version of this on a busy Thursday when I had friends dropping by unexpectedly. It was gone in a flash with everyone asking for seconds.
Ingredients
- Large shrimp: fresh or thawed after previously frozen bigger shrimp means juicy bites that do not overcook
- Ripe avocados: for creaminess choose avocados that yield gently to pressure but are not mushy
- Cherry tomatoes: sweet and juicy opt for multicolored varieties for a pretty look
- Red onion: for crunch and mild bite pick firm onions with glossy skin
- Jalapeno: optional for a touch of heat select one that is glossy and smooth
- Monterey Jack cheese: for gooey melt and mild flavor try to get a block and shred it yourself for best melt
- Sour cream: adds tanginess and keeps things creamy full-fat gives the richest result
- Olive oil: aids in roasting and adds depth use a peppery extra virgin oil if you have it
- Lime juice: brightens and keeps avocado fresh always use fresh lime if possible
- Ground cumin: boosts savory notes buy a small batch for maximum aroma
- Smoked paprika: lends subtle smokiness Spanish style is my favorite
- Salt and black pepper: to season
- Crushed tortilla chips: for a salty crunch use lightly salted or homemade if you want full control
- Fresh cilantro: brings color and an herbaceous lift
Step-by-Step Instructions
- Prepare the Oven:
- Preheat your oven to 400 degrees Fahrenheit or 200 degrees Celsius and lightly grease a medium-sized baking dish to prevent sticking
- Season the Shrimp:
- Combine the cleaned shrimp with olive oil lime juice cumin smoked paprika salt and black pepper in a mixing bowl and toss until the shrimp are evenly coated then let them rest for five minutes so flavors can infuse
- Layer the Vegetables:
- In your prepared baking dish scatter the diced avocados cherry tomatoes red onion and jalapeno evenly across the bottom making sure the colors are distributed for a beautiful final presentation
- Add the Shrimp:
- Arrange the seasoned shrimp in a single layer over the vegetable mixture so they cook through all at the same rate
- Add Cream and Cheese:
- Drop spoonfuls of sour cream evenly over the top and sprinkle everything with the shredded Monterey Jack making sure every bite will get some of the creamy topping
- Bake the Casserole:
- Slide the dish into your preheated oven and bake for fifteen to eighteen minutes watch for the shrimp to turn pink and the cheese to bubble and brown at the edges
- Add the Crunchy Topping:
- Pull the casserole from the oven and right away sprinkle the crushed tortilla chips over the hot cheese so they stick and stay crisp
- Garnish and Serve:
- Chop fresh cilantro and scatter it generously over the top before serving hot straight from the dish
