Hands up if you’ve ever bought ingredients for one meal, only to be left with random bits and pieces afterwards. A half-used pack here, a few vegetables there, sauces waiting quietly in the fridge door.
This is where the fun begins.
I like to think of it as a little kitchen black box challenge — using what you already have and turning it into something new, comforting, and surprisingly delicious. No extra grocery run. No food wastage. Just a little creativity and trust in the process.
These stuffed green peppers came together after a yoshoku-style dinner, when I found leftover Japanese green peppers, some minced beef, and a tiny bottle of unagi sauce that had technically expired two months ago and needed to be used. With garlic, pepper, and spring onion, the sauce became an easy marinade that replaced soy sauce, mirin, and cooking wine all at once.
Stuffed Green Peppers with Minced Beef
Ingredients
- 3 pcs Japanese green bell peppers
- 200 g minced beef can be substituted with minced pork or chicken
- 2 tbsp unagi sauce or teriyaki sauce
- 1 tsp corn starch
- 1/4 tsp black pepper
- 1 clove garlic minced
- 1 tbsp spring onion chopped
- 3 tbsp water for steaming/searing
Simple Sauce Alternative (if not using unagi / teriyaki sauce
- 1 tbsp soy sauce adjust to taste
- 1/2 tbsp mirin
- 1/2 tbsp cooking wine or sake
- 1/4 tsp sugar
Instructions
- Cut the Japanese green peppers in half lengthwise. Remove the stems and seeds. Set aside.
- In a bowl, combine the minced beef, unagi sauce, garlic, spring onion, and black pepper. Mix well by hand until the mixture becomes sticky and evenly combined.
- Cover and chill in the fridge for at least 30 minutes.
- Stuff each pepper half generously with the beef mixture.
- Heat a pan over medium heat and add a little oil. Place the peppers meat-side down and sear for 4-5 minutes.
- Add 3 tbsp water, then cover immediately with a lid. Let them steam for 2-3 minutes, allowing the peppers to soften and the filling to cook through — much like cooking gyoza.
- Cook until the water has evaporated and the meat is nicely browned with lightly charred edges.
- Remove from the pan and serve immediately while hot and juicy.
Notes
- I recommend using Japanese green peppers — they’re thinner, more tender, and give a better texture compared to regular bell peppers.
- If using regular bell peppers, adjust the cooking time slightly as they are thicker and take longer to soften.
