Season the Steak
Pat steak cubes dry with paper towels. Toss with salt, black pepper, and smoked paprika.
Sear the Steak
Heat olive oil in a large skillet over medium-high heat.
Add steak bites in a single layer and cook for 2–3 minutes per side until browned. Remove from skillet and set aside.
Cook the Pineapple
Add pineapple chunks to the same skillet. Cook for 3–4 minutes until golden and slightly caramelized.
Make the Sauce
Lower heat slightly. Add butter and garlic. Stir for about 30 seconds.
Mix in soy sauce, honey, brown sugar, and red pepper flakes. Stir until glossy and bubbling.
Combine Everything
Return steak bites to the skillet. Toss well to coat in sauce and cook for another 1–2 minutes.
Garnish with fresh parsley and serve warm.
