Ingredients for Beef Stir-Fry with Peppers & Crispy Fries
You’ll need the following ingredients to create this complete and delicious meal:
For the Beef Stir-Fry
- 1 pound beef sirloin sliced into strips about 1/4-inch thick
- 2 tablespoons olive oil divided for cooking
- 2 garlic cloves minced
- 1 red bell pepper sliced into strips
- 1 yellow bell pepper sliced into strips
- 2 tablespoons soy sauce or tamari for gluten-free

- 2 tablespoons oil for frying
- Salt to taste
For the Fresh Salad
- Green leaf lettuce about 2 cups
- Cucumber slices about 1 cucumber
- Cherry tomatoes halved, about 1 cup
- Tomato wedges for added freshness
How to Prepare the Crispy Fries
Start with the fries first since they take the longest to cook:
- Cut the Potatoes: Peel 4 large potatoes and cut them into fries about 1/4-inch wide, ensuring they are uniform in size for even cooking.
- Heat the Oil: In a large skillet or deep pan, heat 2 tablespoons of oil over medium-high heat until it shimmers, about 2 minutes.
- Fry Until Golden: Carefully add the potato fries in a single layer and fry for 15-20 minutes, stirring occasionally, until they are golden brown and crispy, then transfer to a paper towel-lined plate and season with salt.
How to Prepare the Beef and Peppers
While the fries finish cooking, prepare the main stir-fry:
- Slice the Beef: Cut 1 pound of beef sirloin against the grain into strips about 1/4-inch thick and set aside.
- Sauté the Beef: In a separate large skillet or wok, heat 1 tablespoon olive oil over medium-high heat for 1 minute, then add the beef strips and cook for 4-5 minutes until browned on all sides, stirring occasionally, then transfer to a clean plate.
- Cook the Aromatics: Add the remaining 1 tablespoon olive oil to the skillet, add 2 minced garlic cloves, and sauté for about 30 seconds until fragrant.
- Add the Peppers: Add 1 sliced red bell pepper and 1 sliced yellow bell pepper to the skillet and stir-fry for 4-5 minutes until they are tender-crisp.
- Combine and Season: Return the cooked beef to the skillet along with 2 tablespoons soy sauce, 1 tablespoon oyster sauce, 1 teaspoon black pepper, and 1 teaspoon paprika, stirring well to coat all ingredients, and cook for another 2 minutes.

Assembling Your Complete Plate
Once all components are ready, it’s time to bring everything together into one impressive meal:
- Build the Salad Base: Arrange 2 cups of fresh green leaf lettuce on a plate or in a bowl as the foundation.
- Add Fresh Vegetables: Top the lettuce with cucumber slices, halved cherry tomatoes, and tomato wedges for a crisp, refreshing contrast.
- Position the Stir-Fry: Place a generous portion of the beef and pepper stir-fry on top of or alongside the fresh salad.
- Finish with Fries: Arrange the golden crispy fries on the plate, seasoning with a pinch of additional salt if desired for extra flavor.
Variations and Customizations
One of the great things about this meal is its versatility and how easily you can adapt it to your preferences!
- Protein Swaps: Replace beef sirloin with chicken breast, pork tenderloin, or even shrimp for a different flavor profile.
- Vegetable Additions: Mix in broccoli florets, snap peas, mushrooms, or onions to add more vegetables and texture to your stir-fry.
- Sauce Variations: Try adding 1 tablespoon of sesame oil or a splash of rice vinegar for tanginess and depth.
- Heat Level: Add 1/2 to 1 teaspoon of chili flakes or a dash of sriracha if you prefer a spicier kick.

Recipe FAQ’s
Can I prepare the components ahead of time?
Yes, you can cut the beef and vegetables up to 4 hours ahead and store them in separate containers in the refrigerator, though it’s best to cook everything fresh for optimal flavor and texture.
How can I make the fries extra crispy?
For extra-crispy fries, pat the cut potatoes dry with paper towels before frying, and ensure your oil is hot enough before adding them so they develop a golden exterior quickly.
What’s the best way to slice beef for stir-frying?
Always slice beef against the grain into strips about 1/4-inch thick, which ensures tender, easy-to-chew pieces that cook evenly in the hot pan.
