You can specify your own widget to use as the LabelFrame 's "label" — this mean, for example, you could create a separate Label widget with the text attributes you want, and specify it when creating the LabelFrame via the labelwidget= option:

import tkinter as tk

root = tk.Tk()
root.geometry('300x75')

label = tk.Label(root, text='Life, the universe and everything?', fg='white',
                 bg='blue')
lable_frame = tk.LabelFrame(root, labelwidget=label)  # Use custom label.
lable_frame.pack(fill=tk.BOTH, expand=1, padx=5, pady=5)

w = tk.Entry(lable_frame)
w.pack(side=tk.LEFT, fill=tk.X, expand=1)

root.mainloop()

Result:
