Baked Crab-Stuffed Avocado
Warm crab folded with Greek yogurt, lemon, dijon, celery, and dill, mounded into avocado halves and baked until heated through, served over a crisp lemon-dressed romaine salad.
Why You'll Love This Recipe
Something that feels a little special, without much effort behind it, is what this lunch is for. It leans on cooked crab and ripe avocado, two ingredients that already taste rich on their own, so the recipe does very little to them beyond a bright, herby binder and a short trip through the oven. It comes together quickly and looks far more composed than the work it takes, which makes it as good for a quiet lunch alone as for setting in front of a guest.
A cool, tangy filling meets a warm, buttery avocado. Baking the stuffed halves just long enough to heat them through softens the avocado and takes the raw edge off the yogurt-and-crab mixture without cooking the crab a second time, so it stays tender rather than turning rubbery. The dijon and lemon cut through the richness, the dill keeps it fresh, and the diced celery folded into the filling adds a small crunch that keeps every bite from feeling too soft. The romaine on the side, dressed simply with olive oil and lemon, gives you a crisp, clean counterpoint to the creamy avocado.
Protein from the crab, healthy fat from the avocado and olive oil, and fiber from the avocado and romaine, so it holds you through the afternoon rather than leaving you hungry an hour later. The Greek yogurt adds extra protein and a creamy texture without the heaviness of a mayonnaise-based filling. It is fresh-tasting and rich at the same time, and because so much of it is whole vegetables and seafood, it feels nourishing without being austere.
Ingredients
- about 480g cooked crab meat
- 4 avocados, halved and pitted
- 1/2 cup Greek yogurt
- 2 celery stalks, finely diced
- 1 tbsp dijon mustard
- 2 tbsp lemon juice
- 3 tbsp chopped dill
- 6 cups chopped romaine
- 2 tbsp olive oil
Instructions
- Preheat the oven: Preheat the oven to 400°F (200°C) and line a baking sheet with parchment or lightly oil a baking dish so the avocados sit level and do not tip while baking.
- Prep the avocados: Halve each avocado lengthwise, twist the halves apart, and remove the pit. Scoop out a little of the flesh from the center of each half with a spoon to widen the well so it can hold more filling. If a half wobbles, cut a thin sliver off its rounded bottom so it rests flat.
- Prep the crab and vegetables: If your crab meat is in larger chunks, flake it gently with your fingers and pick through it to remove any bits of shell or cartilage. Finely dice the celery. Chop the dill. Juice the lemon, keeping a little aside for the salad.
- Mix the filling: In a bowl, combine the flaked crab, Greek yogurt, diced celery, dijon mustard, lemon juice, and chopped dill. Fold gently with a spatula until everything is evenly coated but the crab still holds some texture; avoid mashing it into paste.
- Stuff and bake: Mound the crab filling generously into each avocado well, pressing lightly so it stays put. Arrange the filled halves on the prepared sheet and bake for 10 to 12 minutes, until the filling is warmed through and just beginning to color at the top and the avocado is soft and heated at the edges.
- Dress the romaine and serve: While the avocados bake, chop the romaine and place it in a large bowl. Drizzle with olive oil and the reserved lemon juice and toss until the leaves are lightly coated. Keep the salad plain, since the crab filling is well seasoned on its own. Serve the warm stuffed avocado halves alongside the crisp salad.
Variations
- Spicy kick: Add a pinch of cayenne or a spoonful of finely minced fresh chili to the crab filling, or a few dashes of hot sauce, for gentle heat that plays well against the cool avocado.
- Old Bay style: Season the filling with a little Old Bay or a mix of paprika, celery seed, and black pepper for a classic seafood-shack flavor.
- Extra crunch and color: Fold finely diced red bell pepper and thinly sliced scallion into the filling for more crunch, sweetness, and a pop of color.
- Herb swap: Trade the dill for chopped chives, tarragon, or flat-leaf parsley to shift the flavor while keeping the fresh, green character.
- Cheesy top: Sprinkle a little grated parmesan or panko over the filling before baking for a browned, crisp top; note this adds dairy, and the panko adds gluten.
Storage & Leftovers
The baked stuffed avocados are best eaten soon after they come out of the oven, but leftovers keep in an airtight container in the refrigerator for up to a day. Avocado darkens once cut, so press a piece of plastic wrap directly against the exposed flesh to slow browning; a little discoloration is only cosmetic and still safe to eat. Keep the dressed romaine separate, as it wilts quickly once coated.
To reheat, warm the stuffed halves gently in a 300°F (150°C) oven or toaster oven just until heated through, watching closely so the avocado does not turn bitter or mushy. A microwave works in a pinch but tends to overheat the avocado unevenly, so use short bursts on low power. Dress fresh romaine to serve alongside rather than reheating the salad.
To get ahead, make the crab filling up to a day in advance and keep it covered in the refrigerator; the flavors of the dijon, lemon, and dill actually settle and improve overnight. Halve and fill the avocados only when you are ready to bake, since cut avocado does not hold well, and dress the romaine at the last minute so it stays crisp.
Notes & Tips
- Pick the right avocados: Choose avocados that yield to gentle pressure but are not mushy; too-firm ones will not soften enough in the oven, and overripe ones collapse when you fill them. They should feel like a ripe peach.
- Keep them from tipping: If a filled half rocks on the pan, slice a thin sliver off its rounded underside so it sits flat and the filling stays put while baking.
- Buy the best crab you can: Since the crab is barely cooked here, its quality really shows. Fresh lump or backfin crab tastes cleanest; good-quality canned or pasteurized crab works well too, just drain it and pick through it for shell.
- Season to taste: Crab and yogurt both vary in saltiness, so taste the filling before stuffing and adjust the salt, lemon, and dijon until it is bright and well seasoned.
- Do not overbake: The crab is already cooked, so you are only warming everything through. Pull them once the tops are hot and just golden; longer baking turns the avocado bitter and soft.
- Round out the plate: For a heartier meal, serve the salad with a slice of crusty bread or a spoonful of cooked whole grains alongside; the bread adds gluten.
- Crab and avocado in pepper cups: Mash the avocado with the lemon juice, Dijon, and olive oil, then fold in the crab, celery, dill, and three tablespoons of chopped chives and mound it into halved, seeded red bell peppers. Skip the Greek yogurt and the romaine, and chill it until cold rather than baking it.
Nutrition & Mindful Eating
- Crab and avocado carry each other here. The crab is sweet and delicate and the avocado is rich and buttery, and the yogurt and lemon between them keep two soft things from blurring together, protein and good fat in one shell you eat with a spoon.
- Crab meat is delicate enough to be worth handling gently, folded rather than stirred so the lumps survive, and it brings the protein and the zinc and B12 that make this a lunch rather than a starter.
- Avocado warmed through goes softer and slightly sweeter than it is raw, and it is the source of the richness in every bite, along with the monounsaturated fat and potassium that come with it.
- Greek yogurt makes the dressing creamy and tangy at once, and the Dijon stirred through it gives the filling a low sharpness that stands up to the avocado, with extra protein arriving quietly in the yogurt.
- Celery is the only crunch in a dish of soft things, dill brings its grassy anise note, and the lemon over the top keeps everything sharp, all of it spooned onto cool romaine that snaps under the fork.
- As you eat, take a spoonful with some of everything in it, warm avocado and cool crab and a piece of celery, and notice how much is going on in it before you decide you are still hungry.
Frequently Asked Questions
Can I use imitation crab instead of real crab?
You can, though the flavor and texture will be milder and slightly sweeter, and imitation crab contains added starch and sugar. If you use it, taste the filling and you may want a little extra lemon and dijon to brighten it up.
Will the avocado turn bitter or brown in the oven?
A short bake at 400°F (200°C) just to warm the filling keeps the avocado creamy and sweet. Avocado can turn bitter and mushy if baked too long, so pull the halves as soon as the tops are hot and lightly golden, around 10 to 12 minutes.
Can I serve these cold instead of baked?
Yes. The crab filling is fully cooked, so you can simply mound it into the raw avocado halves and serve without baking for a cool, salad-style version. Baking is just for those who prefer it warm.
What can I use instead of Greek yogurt?
Any thick plain yogurt works, or you can use a spoonful of mayonnaise or mashed avocado for a richer binder. Greek yogurt keeps it tangy and adds protein, so if you swap it, taste and adjust the lemon and salt.
