Oven Packets with Shrimp, Bell Pepper & Fennel
Everything goes into a parchment packet. Shrimp, fennel, bell pepper, a squeeze of fresh orange juice, a hit of chili. The oven turns it into dinner. No pan. No oil. Nothing added except heat.
The sealed parcel traps the citrus steam inside, and in 15 minutes the packet opens to 27g of protein and 15g of fiber at 319 calories, all built on just 4g of fat.

Ingredients
- bell pepper 1
- chili pepper 0.5
- orange 1
- fennel 1
- shrimp (frozen) 4 oz
Method
-
Preheat the oven to 400°F.
-
Slice the bell pepper into thin strips. Remove the seeds from the chili pepper and chop finely. Juice the orange and grate ½ tablespoon of its zest. Remove the green fronds from the fennel and set some aside. Slice the fennel into thin slices, about ⅕ inch thick. In a small saucepan, warm the orange juice with the chili pepper and fennel. Cook the fennel slices until they are al dente, in about 5 minutes.
-
Lay a large piece of parchment paper on your counter. Arrange the fennel on the parchment paper in overlapping layers. Arrange the bell pepper, shrimp and orange zest over it. Drizzle the boiled orange juice over it, adding some chopped chili pepper to taste. Sprinkle everything with some salt.
-
Fold the parchment paper to close it into a packet. Make sure it's sealed properly. If necessary, use a piece of kitchen twine. Place the packet in the oven and bake for 15 minutes.
-
Serve the fennel with shrimp and bell pepper on a plate and garnish with the fennel fronds.
Simmer the fennel in the orange juice for the full 5 minutes before assembling the packet. Raw fennel slices need that head start. Fifteen minutes of oven steam alone won't soften them through, and you'll end up with a crunchy core where you wanted al dente.
Why This Works
Behind this recipe
Is 27g of protein from shrimp enough for one meal?
The widely repeated claim that your body can only use 30g of protein per meal doesn't hold up. Research on protein dosing found that muscle protein synthesis responds effectively across a wide range of intakes, especially from whole-food mixed meals. This recipe's 27g sits comfortably within that range.
Read the full evidence reviewDoes cooking in parchment paper keep more nutrients in the food?
Compared to boiling, yes. When vegetables sit in boiling water, water-soluble vitamins like vitamin C leach into the liquid, and most people pour that liquid down the drain. En papillote cooking works like steaming: the food cooks in its own juice with nothing discarded. This recipe's bell pepper and orange are both rich in vitamin C, and the sealed packet keeps it all on the plate.
Read the full evidence reviewWhere does all the fiber come from?
Mostly from the fennel. One whole fennel bulb delivers roughly 7 to 8 grams of fiber on its own, making it one of the highest-fiber vegetables you can buy. The orange adds another solid contribution. Together they push this meal to 15g of fiber in 319 calories (4.7g per 100 kcal). Research on fiber intake found that higher daily consumption was associated with greater weight loss, likely through its effect on satiety.
Read the full evidence reviewHow does a full dinner have only 4g of fat?
No oil, no butter, no fat added at any step. The shrimp contribute a small amount of natural fat, and everything else (fennel, bell pepper, orange, chili) is essentially fat-free. The en papillote method lets you skip cooking fat entirely because the sealed parchment traps steam from the orange juice, and that steam does the cooking.
