Promising reviews: "There's nothing worse than cooking a delicious meal and then having to clean up a big mess. And baking sheets in particular, which collect grime and grease, can be particularly hard to clean. That's why these silicone baking mats are such a staple in my kitchen. I used to use parchment paper, but these are re-usable and keep my baking sheets cleaner. I just place the mat on my baking sheet and go about cooking whatever I'm making, whether it's roast chicken, veggies, salmon, cookies, or more. When I'm done, I just toss the silicone mat in the sink and clean it, and my baking sheet looks spotless." —Hannah Loewentheil, BuzzFeed Staff
"These baking mats are absolutely fantastic. The quality is superb, and SUCH a good price. I use them for just about everything I put in the oven. From oven pizzas, cookies, you name it! I also love that besides food sliding easily off the non stick surface, they help protect all my baking sheets and such. It’s also super handy to just throw them in the top shelf of the dishwasher or even just wipe clean. Also, an easy tip for storing these, you can cut off about one-third of an empty paper towel roll to use as a holder, and just roll up the mats and slip inside the roll/ring for easy storage of the mats in a drawer. I highly recommend these! Update: I’ve had these mats and we use them almost daily for almost a year now. They still look brand-new and I have had no problems with staining, melting, or the mats becoming worn. When using them, I cook most items at 375 degrees but have used them at up to 425 degrees several times with no issues so far. For clean up, I generally drape them over my cups in the top rack of the dishwasher and then when dry, roll them up and slip a napkin ring or rings cut from an empty paper towel roll so they fit easily into a drawer. These things are fantastic and have paid for themselves many times over in the superior non-stick surface, ease of clean up, and the cost of parchment paper and/or aluminum foil I used prior to discovering these." —Jezzhani
