Bring a large pot of salted water to a boil and cook the noodles according to the package directions. Drain and set aside.
While the noodles cook, season the steak cubes generously with salt and pepper.
Heat olive oil in a large skillet over medium-high heat until very hot.
Add the steak bites in a single layer and sear for about 2 minutes per side until browned. Cook in batches if necessary.
Remove the steak from the skillet and set aside.
Lower the heat slightly and add the garlic for the glaze. Cook for about 30 seconds until fragrant.
Stir in the bourbon, soy sauce, brown sugar, honey, Dijon mustard, Worcestershire sauce, and smoked paprika.
Simmer for 3–4 minutes, then stir in the cornstarch slurry and cook until the glaze thickens slightly.
Return the steak bites to the skillet and toss until evenly coated in the glaze.
In another pan, melt the butter over medium heat and cook the garlic for about 1 minute.
Add the cooked noodles and toss well until coated with the butter and garlic. Stir in the parsley and season with salt and pepper.
Serve the buttered noodles on plates and top with the bourbon glazed steak bites. Spoon any remaining glaze over the top before serving.
