Line a small sheet pan with paper towels and set aside.
Add the oil to the skillet and heat to about 325-350°. When the oil is hot, add one oyster cracker and if it starts to bubble immediately, the oil is hot enough. This is a tester. Cook for 1 to 2 minutes, flipping occasionally until crispy and golden. Use this tester to judge how done you want your fried oyster crackers to be and let it be your guide for the rest of the batch. Remove the tester from the pan before you start frying the first batch.
Add 1 cup of oyster crackers gently to the hot oil and fry, stirring and flipping occasionally for 1-2 minutes or until they're light golden brown and crisp.
Use the spider or slotted spoon to transfer the fried crackers to the paper towel lined pan and immediately sprinkle with half of the seasonings. Toss quickly to coat.
Add the remaining cup of oyster crackers to the hot oil and fry in the same manner. When they're golden and crisp, scoop with the spider or slotted spoon, letting all of the oil drain away before transferring to the sheet pan. Season with the remaining seasoned salt, Bagel seasoning and crushed red pepper. Toss well to coat.
Fried oyster crackers will keep for about 3-5 days in an airtight container or 3-4 weeks in a vacuum sealed container.
