- Sesame oil or neutral oil (1 tablespoon): Adds a subtle nuttiness and helps crisp up the tofu or seitan beautifully in the pan.
- Extra-firm tofu or seitan (14-ounce package): The star protein that absorbs flavors well and gives that satisfying “meaty” texture.
- Cornstarch (1 tablespoon): Creates a light crust on the tofu or seitan, enhancing the texture before cooking.
- Red bell pepper (1, sliced): Brings a sweet, juicy pop of vibrant red color to the dish.
- Green bell pepper (1, sliced): Adds a slightly grassy, fresh bite and a beautiful color contrast.
- Small onion (1, sliced): Gives a hint of natural sweetness and depth when sautéed.
- Garlic (3 cloves, minced): Infuses the dish with aromatic savory notes.
- Fresh ginger (1 tablespoon, minced): Adds a zesty warmth that brightens and balances the flavors.
- Low-sodium soy sauce or tamari (1/4 cup): The salty umami base of the sauce that brings everything together.
- Hoisin sauce (2 tablespoons): Contributes a rich, sweet, and slightly tangy complexity to the stir-fry.
- Maple syrup or brown sugar (1 tablespoon): Sweetens the sauce naturally to balance the savory elements.
- Rice vinegar (2 teaspoons): Adds brightness and a mild acidity that lifts all the flavors.
- Black pepper (1/2 teaspoon): Offers a subtle heat and depth.
- Red pepper flakes (1/4 teaspoon, optional): For those who love an extra kick of spice.
- Water (1/4 cup): Helps to thin the sauce and distribute flavors evenly.
- Cornstarch (1 teaspoon): Thickens the sauce to a glossy finish that clings to each ingredient.
How to Make Vegan Pepper Steak: A Flavorful Plant-Based Stir-Fry Recipe
Step 1: Prepare the tofu or seitan
Before you start cooking, toss the tofu or seitan strips with the tablespoon of cornstarch so they develop a lovely, crispy coating once cooked. This gives the pieces a wonderful texture that holds up well against the sauce and vegetables, making each bite satisfyingly chewy yet crisp.
Step 2: Sear the protein
Heat your sesame or neutral oil in a large skillet or wok over medium-high heat. Carefully add your coated tofu or seitan strips and cook them for 6 to 8 minutes, turning occasionally. The goal is a golden-brown crust that adds a delightful contrast to the tender insides. Once done, set them aside on a plate to rest while you prepare the veggies.
Step 3: Cook the vegetables
In the same skillet, add a touch more oil if needed, then toss in the sliced red and green bell peppers along with the onion. Stir-fry these for about 3 to 4 minutes until they’re just softened but still have a crisp bite. This keeps the dish fresh and colorful. Follow by adding the minced garlic and ginger and cook for an additional minute so their fragrances fill the pan without burning.
Step 4: Whisk the sauce
While the veggies cook, grab a small bowl and whisk together soy sauce or tamari, hoisin sauce, maple syrup or brown sugar, rice vinegar, black pepper, optional red pepper flakes, water, and the remaining teaspoon of cornstarch. This sauce packs a punch with umami and sweetness, thickening as it cooks to coat every ingredient perfectly.
Step 5: Combine and finish cooking
Pour the sauce into the skillet, stirring everything together so the vegetables start soaking up the rich flavors. Return your tofu or seitan to the pan and toss gently, cooking for another 2 to 3 minutes. The sauce will thicken and glaze the stir-fry, ensuring every bite is bursting with flavor and the colors stay vibrant.

Garnishes
Sprinkle freshly chopped green onions or a handful of toasted sesame seeds on top just before serving. These simple garnishes add an extra layer of texture and a fresh pop of flavor that complements the savory sauce beautifully.
Side Dishes
This stir-fry pairs wonderfully with steamed jasmine rice, fluffy quinoa, or chewy noodles. These bases soak up the sauce, making each bite more luscious and fulfilling. Consider adding a side of steamed bok choy or sautéed snap peas for additional greens.
Creative Ways to Present
For a fun twist, serve your Vegan Pepper Steak: A Flavorful Plant-Based Stir-Fry Recipe inside warm lettuce cups for a fresh, hand-held option. Alternatively, spoon it over a bed of cauliflower rice for a low-carb meal that still captures the heart of the stir-fry flavors.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer leftovers to an airtight container and store them in the refrigerator for up to 3 days. The flavors actually deepen overnight, making it a great option for a quick, tasty lunch or dinner later in the week.
Freezing
You can freeze this dish, although for best texture, freeze the tofu or seitan separately from the vegetables and sauce if possible. Stored properly in freezer-safe containers, it will keep well for up to 2 months.
Reheating
To reheat, gently warm the stir-fry in a skillet over medium heat to help retain the crispness of the vegetables and tofu or seitan. Add a splash of water if the sauce becomes too thick during reheating, stirring until warmed through.
FAQs
Can I use other proteins besides tofu or seitan?
Absolutely! Tempeh or even plant-based meat substitutes can be tossed in to give a different texture and flavor while still keeping the dish vegan and protein-packed.
Is this recipe gluten-free?
It can be, as long as you use gluten-free tamari instead of soy sauce and ensure that the hoisin sauce is gluten-free. Always double-check your ingredient labels to be safe.
Can I add other vegetables?
Definitely! Broccoli, snap peas, mushrooms, or baby corn all make excellent additions and can add new dimensions of texture and flavor to your Vegan Pepper Steak: A Flavorful Plant-Based Stir-Fry Recipe.
How spicy is this dish?
The spice level is mild by default, thanks to the black pepper and optional red pepper flakes. You can adjust the heat by adding more or leaving out the red pepper flakes entirely to suit your taste.
What should I serve this with for a complete meal?
Serving this stir-fry over steamed rice, noodles, or quinoa rounds out the protein and veggie mix with satisfying carbs, creating a nourishing, balanced meal that hits all the right notes.
