Sheet pan dinner: Roasted white fish and cabbage tacos

Roasted white fish, cabbage, and scallion tacos that all cook together on a sheet pan.
Roasting the fish, scallions, and cabbage on a sheet pan make an easy weeknight taco night with almost no clean up.

The dog days of summer are here in the Northeast and it. is. sweaty. I'm hankering for things that are raw or minimally cooked, so a sheet pan dinner may seem counterintuitive. But the cooking here is very quick, requires very few dishes, and the end product leaves us feeling satisfied, but not stupified because being really hot and really full is like entering the third ring of hell.

Taco night, but easier, healthier, and more interesting.

(As always, skip to the next photo to avoid the toddler update.)

Speaking of hell (KIDDING), we're in that annoying place where the things our kid does seem SO AWFUL to us, but when I tell others about his behavior, I'm usually met with, "Yeah, that sounds about right for a 3-year-old." For instance, I just about blacked out with rage (though I think I handled it okay), when M aimed his stream directly at the back of the toilet instead of into the bowl, effectively spraying our entire bathroom with pee. He thought this was HILARIOUS, while I floated out of my body and burst into a million pieces. The first person I told about this replied, "If he ever has a brother, they'll probably do it together."

Don't get me wrong, it's VERY comforting when other people are completely unfazed by M's behavior. But I'm still left wondering if I'm the world's least effective parent. It can be hard to process.

But I also get it. When I tell someone else about M's behavior that's driving me crazy, to them, it's an isolated incident. But when I'm asking him to put on his shoes for the 20th time after struggling to get him to do five other things in the past hour, that shoe battle feels so much more intense and difficult.

Basically what I'm saying is that 3 has been a tough age so far and that on exhausting days, the last thing I want to do is fight with dinner too (what a segue, huh?).

The white fish roasts on a bed of lemons and limes.

This dinner is partly steamed and partly roasted. Roasting the fish with the veggies proved counterproductive because a lot of liquid came out of the fish while it cooked, which led to steamed veggies instead of roasted ones. No thanks. 

Green and red cabbage are perfect for roasting with fish because they cook fast and get both melty and crispy.

Instead, you're going to wrap up the fish on a bed of lemon and lime in parchment bundles and let them steam on top of the cabbage and scallions to achieve the best of both cooking methods while still only using one pan. Because, it's hot. Here is a handy illustration of my favorite folding method:

So! Wrap up the fish and let it steam in the citrus. Chop the cabbage and scallions, toss with some olive oil, and throw the whole mess into the oven. While it's cooking, heat some taco shells, whizz some avocado crema in the blender, and prep any other toppings you might want (cheese, tomatoes, jicama, beans, etc). Tonight's dinner can be ready in about 30 minutes and is a nice departure from the usual taco night.

Wrapping the white fish in parchment packages helps retain their moisture while also letting the cabbage and scallions get roasted and crispy. It also decreases the mess even more.
Parchment contains the moisture so that the fish steams while the veggies roast.

Roasted cabbage fish tacos with avocado chipotle crema  

½ small head of red cabbage, roughly chopped
½ small head of napa cabbage, roughly chopped (about 6 cups total cabbage)
8 scallions, trimmed and cut in half width-wise
2 Tbsp olive oil
1 large lemon
3 large limes, divided
1 ¼ lb cod or other firm white fish (four medium fillets)
1 Tbsp mayo
1 large avocado
Juice of 1 lime (about 1-2 Tbsp)
4-6 Tbsp water
1 small clove garlic
1-2 tsp chipotles in adobo or chipotle hot sauce
1/2 tsp kosher salt
12 corn tortillas

Preheat oven to 400.

Toss the cabbage and scallions with 2 Tbsp of olive oil and salt and spread onto a baking sheet. Set aside.

Slice the lemon and one of the limes. Spread out four sheets of parchment paper or tin foil on your countertop. Place 2 or 3 slices of the lemon and lime in the middle of the parchment. Place one fish filet onto the citrus bed and sprinkle with salt and pepper.

To fold the bundles, bring the edges of the two longest sides of the parchment together and fold over three or four times until you can’t fold anymore without hitting the fish inside. Next, fold the sides toward the middle until you’ve made a tight rectangle around the fish. Place on top of the veggies, making sure to move the scallions out from beneath the fish and toward the edges of the sheet pan.

Roast until the veggies are wilted and lightly browned and the fish flakes easily with a fork, about 15 minutes. If desired, carefully remove the fish bundles, being aware of steam that might escape, and roast the veggies for another 5 minutes.

Meanwhile, make the chipotle avocado crema. Combine the mayo, avocado, lime juice, water, garlic, chipotles or hot sauce, and salt in a blender or food processor and blend until smooth. If too thick, scrape down the sides and add more water a little bit at a time and blend again until you've reached the right consistency. 

Toast the corn tortillas and prep any other fixings you might want with your tacos (cheese, more avocado, beans, tomatoes, etc). Squeeze some more lime juice over the assembled tortillas and serve.

Yield: 4 servings of three tacos and 1 fish fillet each

Taco night and sheetpan dinner night in one! No mess!
Colorful and healthy family taco night.
Roasted cabbage and scallions are mellow enough for toddlers and picky eaters.

Sheet pan dinner: Chicken, potatoes, poblanos, and scallions

Sheet pan dinner: chicken thighs with poblano peppers, potatoes, and scallions.

Guys, this is one of the fastest, easiest dinners you can make. As long as the chicken is defrosted (always dicey in our house as I am notorious for leaving things in the freezer), this can be on your table about 30 minutes. Ready...go! 

Fresh poblano peppers and scallions mellow considerably when roasted.

I love a sheet pan dinner for so many reasons. It's fast. The cleanup is easy. Roasting is a simple way to add flavor and texture by using heat to crisp and caramelize everything. And obviously, wrapping things in a tortilla and serving it in a taco truck like this one is a surefire way to get my toddler to eat anything.

AND, this sheet pan is customizable for any dietary need. Want gluten-free? Choose corn or gluten free tortillas. Doing a Whole 30 or following a Paleo diet? Forget the cheese and tortillas altogether or eat this as a hearty salad over greens with avocado and an olive oil and lime dressing. Vegetarian or vegan? Swap in tofu for the chicken or increase the veggies and put the spices directly onto the potatoes. See? Something for everyone.

This Tex-Mex rub is cumin, oregano, chili powder, coriander, garlic powder and salt.

A couple of notes:

  • I've listed two tablespoons of oil in the ingredients, but use the second tablespoon sparingly. The fat that renders from the chicken when cooking is usually enough for the potatoes and other veggies. I spray the parchment with olive oil before adding the potatoes to prevent sticking and then let the chicken fat do the rest of the work.

  • The poblano peppers and chili powder that I've used in this recipe are really mild and fine for my almost-3-year-old. If you're concerned about spiciness, feel free to sub a can or two of roasted poblano peppers that are marked "mild" and don't cook them; just stir them into the hot veggies and chicken at the end. Also, taste your chili powder before using it to gauge its heat. If it feels too hot for your kiddos, swap in an equal amount of paprika or skip it altogether.

Ingredients list: chicken thighs, scallions, poblano peppers, and potatoes. Add olive oil and a Tex-Mex spice mix for a sheet pan dinner that will please the entire family.

Sheet pan chicken with potatoes, poblanos, and scallions

2 lb skinless boneless chicken thighs
2 Tbsp olive oil, divided
1 tsp cumin
½ tsp Mexican oregano (or regular oregano)
½ tsp mild chili powder
½ tsp coriander
½ tsp garlic powder
½ tsp kosher salt
1 lb Yukon potatoes
2 large poblano peppers
1 bunch scallions

Preheat the oven to 425. Cover a large sheet pan with parchment paper or tin foil and set aside.

In a large plastic bag, combine the chicken, 1 Tbsp of olive oil, and the dry spices. Close the bag tightly and shake and squish around to combine and distribute. I like to mix the spices together in a small jar to avoid any pockets of one flavor, but that’s not strictly necessary. Set aside.

Chop your potatoes into medium-small cubes. Mine are about 1 inch long and ½ an inch wide, but every potato is shaped differently. You want your cubes to be small enough that they’ll roast quickly, but large enough that they won’t turn to mush.

Lightly oil the parchment and then spread the potatoes in a single layer on the parchment-covered pan (see note above). Sprinkle the potatoes VERY lightly with salt. (There's a fair amount of salt and spice on the chicken that will transfer to the veggies during cooking, so don't go overboard.) Remove the chicken from the bag and place the pieces on top of the potatoes.

Roast for 12 minutes.

While the chicken and potatoes are cooking, slice the poblanos into thin sticks. Trim the hairy bottoms and any yucky bits from the scallions. Set aside.

After 12 minutes, remove the pan from the oven and scatter the scallions and peppers evenly over the pan. Using tongs, carefully fish out the chicken pieces and place them on top of the scallions and peppers. Put the whole shebang back into the oven and cook for 5 more minutes until a thermometer in the thickest part of the chicken reads at least 165.

Remove the chicken with tongs and set aside. Continue to cook the vegetables for 5 more minutes or as needed to reach your desired doneness. We're usually set after 5 minutes.

See serving suggestions above, but however you eat this roasted goodness, first SPRINKLE ALL OF IT WITH LIME JUICE!
