There are multiple methods to grease pans or baking dishes without nonstick spray. You can use paper towels, parchment papers, basting brushes, or even your fingers. If that's too messy, you can always purchase a refillable spray bottle and fill it with your preferred cooking oil. It's great to use when greasing your pan or even lightly spritzing dishes and salads rather than pouring too much oil or heavy dressings.
