Xomoo Silicone Freezer Tray: An Honest Review After the Honeymoon

Every product I love has a honeymoon. The first month I forgive everything. The tray wobbles, I forgive it. The lid takes two hands, I forgive that too. It is only after the second month, standing over the chest freezer in the garage on a Sunday night, that I find out what I actually think. So here is the honest version, the one I would give a friend who is thinking about buying the Xomoo silicone freezer tray for her dog's homemade meals. I spent thirty years running a school cafeteria, so I have opinions about portion control, and I have been batch-cooking for Biscuit, my nine-year-old beagle mix, since his stomach started turning up its nose at kibble. This tray has been in the rotation the whole time.

The honest summary is this: the Xomoo tray is a good tool, and I would buy it again. It is not a perfect tool, and the things that annoy me are the same things that annoy me about every silicone mold I have owned. But for the specific job of freezing dog food in measured portions, it has quietly become the thing I reach for first. In this review I will tell you what it is like after the honeymoon, what nobody tells you about the lid, where it falls short, and exactly who should buy it and who should keep scrolling.

How I've Used It

Every Sunday afternoon I cook for Biscuit. It is not elaborate. I simmer a protein, usually chicken or turkey, with whatever vegetables are in the fridge, let it cool, and portion it into the freezer. Before the Xomoo tray arrived, I used a mix of glass containers and plastic tubs, and the system worked, but it had a flaw. Glass takes up space and takes forever to thaw. Plastic tubs freeze in awkward shapes, and I could never remember what was inside. The Xomoo tray changed the rhythm. I fill it, put the lid on, and by the time I finish the dishes, I have four neat 500ml portions waiting for the chest freezer in the garage.

The portion marks are the feature I did not expect to care about. Each of the two cavities holds a full two cups, with a molded line at 250ml and another at 500ml. For Biscuit, who is about 28 pounds of opinionated beagle, one 250ml portion is a meal. When I am cooking for my own freezer, I fill to the 500ml line and get a proper bowl of soup. The marks are molded into the silicone, so they do not wash off, and I can read them without putting on my glasses, which is more than I can say for the measuring cups in my drawer.

I have used the same two trays every week since they arrived, which is roughly four months of Sunday cooking. They have been frozen, thawed, washed in the dishwasher, and occasionally left on the counter overnight. The silicone still flexes the way it did on day one, the lid still snaps on, and the trays have not warped or cracked. The manufacturer says they are oven safe up to 428°F, which I have not tested, because I have no reason to bake a dog dinner. But the fact that they survive the dishwasher matters more to me than any oven claim.

What Nobody Tells You About the Lid

Here is the part I did not read in any listing. The clear silicone lid is genuinely leak proof, but it only works if you press it down all the way around. The first time I filled the tray with thin chicken broth, I set the lid on top and walked away. By the time I reached the garage, there was broth on my shirt and a puddle on the floor. The lid had sealed in the middle but not at the corners. Now I run a finger around the whole edge before I lift anything, and I have not spilled a drop since. The listing says leak proof, and it is, with the same caveat that applies to every lid I have ever owned: you have to close it properly.

The second thing nobody tells you is that a full tray is floppy. Silicone is flexible, which is exactly why the portions pop out so easily, but a full tray of stew will sag in the middle if you carry it like a book. I learned to carry it with two hands, flat, like a tray, which it is. When I am filling it, I set it on a sheet pan first. That one habit solved the wobble, and it also means the tray slides into the chest freezer without catching on the wire shelves.

And the third thing is that frozen food does not stick to silicone the way it sticks to plastic, but it does not release itself either. You still have to flex the tray. The good news is that a gentle push from underneath pops each 500ml cube out whole, and the tray is back in the sink before the cube has started to thaw. No hot water, no twisting, no prying with a knife.

What I Actually Use It For

The obvious use is dog food, and that is what I bought it for. Biscuit gets a rotation of chicken and rice, turkey and pumpkin, and a beef stew that he would probably eat straight from the pot if I let him. Each Sunday I fill one tray to the 250ml line for his meals, and I use the second tray for whatever I am cooking for myself. But I have also used these trays for chicken stock, tomato sauce, and the leftover chili that would otherwise sit in the fridge until it became a science experiment. A 500ml block of stock thaws in the time it takes to boil pasta, and it stacks neatly in the chest freezer next to Biscuit's portions.

The 2-pack matters more than I expected. One tray gives you two 500ml cavities, which is not enough for a week of dog meals. Two trays give you four, which is exactly one week of Biscuit's dinners, or two days of soup for a household. If I had bought a single tray, I would have been annoyed within a month. The fact that the pack comes with two is the reason it still lives on my counter.

How It Compares to What I Used Before

I do not want to oversell this tray, so let me be direct about what it replaced. My old system was glass containers and plastic tubs, and it worked. But glass is heavy, it thaws slowly, and every container in my freezer seemed to hold a different amount. The Xomoo tray is the opposite: every portion is the same size, clearly marked, and frozen flat enough to stack. When I need one meal for Biscuit, I pop out a single 250ml cube and put the rest back. With glass, I was thawing an entire container because I could not get a clean half out of it.

There is one more comparison worth making. I tried a standard ice cube tray before I bought this one, the kind meant for water and coffee. It made portions that were too small, it was impossible to get a lid onto, and the cubes tasted like whatever had been in the freezer before them. The Xomoo tray is a different category of tool. It is built for food, it has real portion marks, and it comes with a lid that keeps the broth off everything else in the freezer. That last part matters more than you would think.

I will also say this about the comparison: the tray has changed how I think about the freezer itself. Because the portions are flat and uniform, they stack like bricks. I can fit a week of Biscuit's meals in one corner of the chest freezer, with room left over for a casserole and a bag of peas. With my old round containers, I was always playing freezer Tetris, and something always ended up buried at the bottom. That is not a feature on the box, but it is the feature I notice most.

Cleaning and Care

Cleaning is where this tray earns its keep. Both trays go in the dishwasher, which is non-negotiable for me after a Sunday of cooking. They come out clean, including the corners where the marks are molded in. I will say that silicone can hold onto odors, so I do not freeze fish in these trays, and I rinse them right after use if I have stored something strongly flavored. A quick rinse and a spot on the drying rack is the whole routine.

One note about the oven claim. The specs say the trays are oven safe up to 428°F, and I believe it, but I have never needed to test it. I use them for freezing and storing, and occasionally for defrosting a portion in the microwave. Actually, let me be careful there: I do not microwave the tray itself. I pop the cube out, put it in a bowl, and warm it that way. The tray goes back to the freezer, and the bowl goes in the microwave. That is the routine that has worked for four months.

Where It Falls Short

Now the honest part. The tray is not perfect, and I want you to know what you are getting. First, the lid takes two hands to seat properly, especially when the tray is full and the silicone wants to flex. Second, the cavities are large. If you have a small dog, a two-cup cavity is a lot of food, and you will rely on the 250ml mark every single time. Third, silicone can hold onto odors, which is why I keep fish out of these trays. Fourth, the trays are not stackable when full, because the lid is flat but the food inside is not. They stack fine in the freezer once the portions are frozen and the cubes are out of the trays.

None of those are dealbreakers. They are the difference between a product that looks good in a listing and a product that works in a real kitchen. I would rather know about the floppy tray and the two-hand lid before I buy than discover them on a Sunday night with a pot of stew cooling on the stove.

Four 500ml portions, one tray, about five minutes of filling, and every single one pops out clean, even after four months of Sunday cooking.

Who This Is For

This tray is for someone who batch-cooks for a dog with a sensitive stomach, or for themselves, and wants portions they can actually measure. It is for the person who has a chest freezer in the garage and a Sunday routine. It is for the person who is tired of thawing an entire block of stew when they only need one meal. If that sounds like you, the Xomoo tray will earn its place on your counter. And if you are cooking for your dog, please run the recipe past your vet first. I check every new ingredient with Biscuit's vet, because a homemade diet is only a good idea when it is a balanced one.

Who Should Skip It

This tray is not for everyone. If you feed your dog kibble and only occasionally make broth, a regular ice cube tray or a few glass jars will do the job. If you need single-serving portions for a small dog, the two-cup cavities will feel oversized, and you will spend your time filling to the 250ml line and wishing for a smaller mold. And if you are the kind of cook who hates washing anything by hand, silicone still needs a rinse even after the dishwasher, because the marks catch food. None of that makes the Xomoo a bad tray. It just means it is a tool for a particular job, and the job is batch cooking.

The Bottom Line

I keep coming back to the same sentence when people ask me about this tray: it does what it says, and it does it without drama. The portions are the size the marks say they are, the lid keeps broth where it belongs, and the frozen cubes come out when I need them. Four months in, nothing has cracked, warped, or started to smell like the garage freezer in a Wisconsin winter. I am not the kind of person who gets excited about kitchen plastic, silicone or otherwise, but I am the kind of person who notices when a tool quietly works every single week.
