Ingredients

For the Stir-Fry:

1 lb (450g) mixed mushrooms (cremini, shiitake, button), cleaned and sliced
3 bell peppers (mix of red, yellow, green), seeded and thinly sliced
1 medium onion, thinly sliced
4-5 cloves garlic, minced
2-3 tablespoons neutral oil (avocado or vegetable)
1 tablespoon toasted sesame oil

For the Sauce:

3 tablespoons low-sodium soy sauce or tamari
1 tablespoon vegetarian oyster sauce (or regular)
1 tablespoon honey or brown sugar
1 teaspoon rice vinegar
½ teaspoon red pepper flakes (optional, adjust to taste)
1 teaspoon cornstarch + 2 tablespoons water (slurry, optional)

Garnish:

Sliced green onions
Sesame seeds

Instructions

Let's dive in—this colorful stir-fry comes together super fast, so get everything prepped and ready first!
Clean mushrooms (wipe with damp cloth), slice them evenly; slice bell peppers into thin strips, onion thinly, and mince garlic—have sauce ingredients whisked in a small bowl.
Heat a large wok or skillet over high heat until very hot—add neutral oil and swirl to coat.
Add mushrooms in a single layer (batch if needed)—stir-fry 3-4 minutes, letting them brown and release moisture without constant stirring for golden edges.
Push mushrooms aside, add a drizzle more oil if needed, then toss in onion and garlic—stir-fry 1 minute until fragrant and onion softens slightly.
Add sliced bell peppers—toss everything together and cook 2-3 minutes until peppers are crisp-tender and vibrant.
Pour in the sauce—stir well to coat all veggies; let it bubble and thicken for 1 minute.
For glossy sauce, stir in cornstarch slurry and cook 20-30 seconds until silky and clinging.
Drizzle toasted sesame oil over top for nutty aroma—toss in most green onion slices and give one final mix.
Serve hot over rice or noodles—sprinkle sesame seeds and remaining green onions. Grab your fork (or chopsticks!) and enjoy the juicy, garlicky goodness!

Notes

High heat is key for texture—keep it cranked! Best eaten fresh, but reheats well with a little added liquid. Double sauce if you love it extra flavorful.

Recipe Tips and Tricks

Use high heat and a hot pan/wok to sear mushrooms without steaming them—pat dry first for best browning.
Don’t overcrowd; cook in batches if your pan is small to avoid sogginess.
Slice bell peppers and mushrooms uniformly for even cooking and pretty presentation.
Add garlic after mushrooms start browning to prevent burning and bitterness.
Prep sauce and veggies ahead—stir-frying happens fast once heat is on.
Taste sauce before tossing; adjust soy, honey, or vinegar for your ideal balance.
Finish with a cornstarch slurry for glossy, restaurant-style sauce that clings perfectly.

Ingredients Notes

Mushrooms are the hearty star—cremini (baby bella) or button offer mild earthiness and firm bite; shiitake add deeper umami and chew; a mix elevates flavor and texture. Bell peppers (red, yellow, green) bring sweetness, crunch, and vivid color—use a variety for visual appeal and balanced taste.

Fresh garlic provides pungent aroma that mellows into nutty sweetness. Onion (yellow or green) adds subtle sharpness and base flavor. Soy sauce (low-sodium) delivers salty umami; oyster sauce (vegetarian if preferred) boosts richness.

A touch of honey or sugar balances saltiness. Rice vinegar brightens; toasted sesame oil adds nutty finish at the end. Optional red pepper flakes bring heat, while cornstarch slurry creates silky texture. Neutral oil like avocado handles high heat without smoking.

Variations and Substitutions

Make it vegan with tamari and vegetarian oyster sauce. Add protein: tofu cubes (crispy pan-fried), chicken, shrimp, or beef strips—marinate first. Swap mushrooms for portobello for steak-like texture or add broccoli, snap peas, zucchini, or carrots for more veggies.

Use different peppers or include jalapeños for spice. For Indian-inspired twist, add black pepper, fennel, curry leaves instead of soy sauce. Go buttery with garlic butter. Sweeten with maple syrup.

Gluten-free: tamari and gluten-free oyster sauce. Toss in cashews or peanuts for crunch. Serve over cauliflower rice (low-carb), quinoa, or noodles. Garnish with basil, cilantro, lime, or sesame seeds for fresh flair.

Storage Options

Store leftovers in airtight container in fridge up to 3 days—flavors improve slightly! Reheat in hot skillet with splash of water to refresh crispness; microwave softens texture more. Not ideal for freezing—mushrooms and peppers become mushy.
