Xomoo Silicone Freezer Tray Review: Months of Weekly Use in a Home Dog Kitchen

Biscuit, my 9-year-old beagle mix, spent most of last winter walking away from his bowl. We tried three kibbles, two toppers, and one very expensive canned food that he ate for exactly four days. Our vet finally suggested I try cooking some of his meals at home, and that is how I ended up with a Sunday afternoon routine I never planned on: batch cooking for a 28-pound dog with a sensitive stomach.

The routine works, but the freezing part was the weak link for months. I tried glass containers, plastic deli tubs, and one ambitious ice cube tray that made portions too small to bother with. Then I bought the Xomoo Silicone Freezer Tray, a 2-cup tray that makes four 500ml portions at a time. I have used it every single week since, and this review is the honest long-term report.

How I've Used It

Every Sunday afternoon, I cook a big batch of Biscuit's food: a lean protein, a couple of vegetables, and a starch, all simmered until soft and then cooled. I portion it into the Xomoo tray while it is still warm but not hot, snap the clear silicone lid on, and set the whole thing in the freezer. The tray sits flat on the shelf, and the four compartments each hold a full 500ml portion, which is exactly what Biscuit eats per meal.

When a portion is needed, I pop the tray out of the freezer, run the bottom under warm water for about twenty seconds, and push from the underside. The silicone gives just enough that the block slides out whole, no chiseling, no melted edges. I thaw it in the refrigerator overnight and warm it gently before serving. The 250ml and 500ml marks molded into each compartment mean I can also make smaller portions for the days when Biscuit is less hungry, or when I am cooking for a friend's small dog.

One Sunday in early February stands out because I nearly ruined a whole batch. I had made ground turkey, carrots, and white rice, and I filled each compartment right to the rim, reasoning that more food per tray meant fewer trays in the freezer. The lid still snapped on, but the silicone flexed at the corners and the seal looked strained. The next morning there was a thin line of frost on the freezer shelf under the tray. Nothing had leaked, but I had clearly overfilled. The batch itself was fine, and Biscuit ate those portions without complaint, but the frost told me the seal was working harder than it should. Since then I fill each compartment to just below the rim, and I have not seen frost again. That one mistake taught me that the tray's capacity is generous but not unlimited, and the 500ml mark is the fill line I trust.

A note on my kitchen: I cook in an ordinary home kitchen and store the frozen portions in a chest freezer in the garage. The tray is 10.75 by 4.92 by 2.17 inches, so it stacks neatly on the freezer shelf next to my own leftovers. I own one set of two trays, and that is enough for a week of portions with room to spare.

Why Portion Size Matters More Than You Think

The single biggest reason my earlier freezer attempts failed was portion size. My first ice cube tray made cubes that were too small, so I thawed four or five at a time and they thawed unevenly. Glass containers held the right amount, but the food froze into a solid block that took hours to thaw and always left a puddle of separated liquid. The Xomoo tray solves both problems at once because each compartment is scaled with 250ml and 500ml marks, and the tray makes four 500ml portions per fill.

For Biscuit, one 500ml portion is one meal. I know exactly how much he is getting, which matters because our vet asked us to keep his portions consistent while we figure out what his stomach tolerates. The molded marks take the guesswork out of it, and the rectangular shape means the frozen block fits neatly into a bowl or a small saucepan for gentle warming.

The glass container failure is worth describing in detail because it is the one most people will recognize. I used a 2-cup glass container with a plastic lid, the same kind I already owned for my own leftovers. The first time I froze a batch of Biscuit's food in it, the portion froze into a solid cylinder that took almost eight hours to thaw in the refrigerator. When I finally got it out, the texture had changed: the liquid had separated and pooled at the bottom, and Biscuit, who is picky about texture, turned his nose up at it. I tried warming it in a saucepan, but the outside heated while the middle stayed cold, and I ended up serving lukewarm mush. The flat rectangular portions from the Xomoo tray thaw in a fraction of that time, and because each portion is a consistent thickness, it warms evenly.

The Xomoo brand has become a regular in my kitchen, and the Xomoo tray is the one I recommend when friends ask how I manage the freezer part of batch cooking. It does the job quietly and well, and after months of weekly use I have not had a single portion fail to release.

After months of weekly use, every single portion has popped out whole. That is the whole job, and the Xomoo tray does it every time.

The Lid, the Seal, and the Leak Test

The included clear silicone lid is the feature I was most skeptical about. I have owned freezer containers with lids that warped, cracked, or simply refused to stay on. The Xomoo lid snaps over the tray and seals well enough that I can stack a second tray on top without worrying about spills. The manufacturer describes it as leak-proof, and in my experience that is accurate for liquid-heavy stews and sauces.

I ran the leak test on a Tuesday in March with a batch of turkey broth and vegetables, the soupiest thing I make. I filled both compartments to the 500ml mark, sealed the lid, and then did something I would not normally do: I set the tray on its side in the freezer and left it for an hour. When I checked, the tray was still on its side, the shelf was dry, and the only evidence of the experiment was a small dent in the soft silicone where it had rested against the rack. I have also carried a full tray from the kitchen counter to the garage freezer with one hand, down the back steps, and the lid has never popped off. That matters more to me than any lab claim, because the walk to my chest freezer is the most likely place for a spill. I have also learned to seat the lid before the tray goes in the freezer, because a full tray is harder to seal once the food has settled.

One honest caveat: the lid is not a hard lid. If you stack heavy items directly on top of it, the silicone will flex. I keep the trays on their own shelf in the chest freezer, and that has been enough. The lid is also clear, which makes it easy to see what is inside without opening the freezer door and letting all the cold air out.

Cleaning, Durability, and the Dishwasher Question

The manufacturer says the Xomoo tray is oven-safe up to 428°F and dishwasher-safe. I use the dishwasher for the tray and the lid after each batch, and both come out clean with no warping, no staining, and no lingering odor. The silicone does not absorb the smell of fish or liver the way plastic containers did in my kitchen.

The fish test was the one I dreaded most. Plastic containers in my kitchen have a long memory for salmon, and I expected the silicone to hold onto that smell for weeks. I froze a batch of salmon and sweet potato in early April, served the last portion about ten days later, and ran the tray through the dishwasher on the top rack. When it came out, I put my nose right up to the silicone. Nothing. No fish smell, and the next batch of turkey went in without any hint of the previous occupant. I also checked the molded measurement marks, because those are the first thing I expected to wear away. They are as legible as they were in January, which tells me the silicone is holding up better than the plastic tubs it replaced.

I have also baked with the tray, using it as a mold for small meat loaves. The silicone handled the heat without any issue, and the rectangular portions released just as easily as the frozen ones. If you only use it for freezing, that oven-safe rating is a bonus you might never need, but it is nice to know the tray is not a one-job tool.

After months of weekly use, the tray shows almost no signs of wear. The silicone has not cracked, the corners have not torn, and the lid still seals. The whole thing weighs 1.1 pounds, so it is light enough to handle easily when full, and the two-pack means I always have one tray in the freezer and one in the dishwasher.

What I Wish Someone Had Told Me

First, the tray is large. The dimensions are 10.75 inches long, 4.92 inches wide, and 2.17 inches high, which means it takes up meaningful space on a freezer shelf. It stacks well, but it is not a tiny ice cube tray. Measure your freezer shelf before you buy, especially if you have a small freezer compartment above the refrigerator.

Second, the portions are big. Each compartment holds a full 500ml, which is a generous meal for a small dog and a large meal for a medium dog. If your dog eats less than that, you will either split the portions or use the 250ml mark and freeze half portions. I occasionally do the latter for Biscuit on days when he is less hungry, and it works fine, but the tray really shines when you want consistent, generous portions.

Third, warm food should go into the tray only after it has cooled. The tray is oven-safe to 428°F, so it can handle heat, but pouring hot liquid directly into the silicone and then into the freezer will create a lot of frost and slow the freezing process. I let my batches cool to room temperature first, and the portions freeze faster and more evenly.

Who This Is For

The Xomoo silicone freezer tray is for anyone who batch cooks for their dog and wants the freezer part to stop being the hard part. If you make a week or a month of portions at once, if you want consistent meal sizes that your vet can help you plan around, or if you are tired of thawing a solid block of glass-container stew, this tray will feel like a small relief.

It is also a good fit if you cook for yourself. The same tray that holds Biscuit's turkey and sweet potato mix also holds my own soup and sauce portions. The 500ml size is a sensible single serving for a human, and the oven-safe silicone means it can go from freezer to oven for reheating. That versatility is why the Xomoo tray has earned a permanent spot on my counter.

Who Should Skip It

If your dog eats very small meals, or if you prefer to freeze individual servings in smaller portions, the 500ml compartments may be more than you need. You can use the 250ml marks and freeze half portions, but if that is every meal, a smaller tray with more compartments might suit you better.

If your freezer space is tight, measure carefully. The tray is 10.75 inches long and 4.92 inches wide, and while it stacks neatly, it does take up a real footprint. And if you only freeze dry food or feed exclusively kibble, you simply do not need a freezer tray at all. This is a tool for people who cook, not a gadget that earns its place on its own.
