Cut the florets into medium-sized florets.Too small and they’ll burn.
Make sure the florets are uniform in size.Making sure they’ll all the same size, allows them to cook the same.
Place them onto the baking sheet in a single layer.Vegetables let off moisture as they cook and if they’re piled on top of one another they will steam and not roast.

First, take care not to overcrowd your pan; if the cauliflower is packed in rim-to-rim, the moisture will not be able to escape as the florets cook, which will result in soft steamed cauliflower instead of roasted. Next, don't be overly generous with the oil — a light coating is what we're after here.
If you're planning to roast the cauliflower whole or slice it into steaks, slice off the thick stem at the base. Drop the whole cauliflower head upside-down into cool, salted water. Let it soak for 10 to 15 minutes to remove dirt, residue and bugs.
Although there are some tricks to apply if you overcook vegetables, your best bet is to aim for undercooking the vegetable a little. Think al dente texture, which should mean a maximum of 5 minutes, but probably more like 3 minutes of cooking time for your florets.
Cauliflower has a very high water content, so it won't get crispy if you bake the florets crowded together. "Be sure to give each floret a bit of room so that the they have space for airflow. I'd also recommend baking them on a silicone baking mat," says Blay.
If you crowd and overlap the veggies, they will steam and get mushy, not what we want! Roast vegetables at a high heat, 425 degrees F and make sure you preheat the oven so it is HOT when the veggies go in! Flip! For even browning and caramelization, flip vegetables halfway through cook time.
Adding vinegar to the cooking water when cooking cauliflower is a common technique that can help to reduce the strong sulfur smell that cauliflower can sometimes give off while cooking. The vinegar can help to neutralize the sulfur compounds in the cauliflower, resulting in a milder aroma and flavor.
Cauliflower contains some phytonutrients, these nutrients may react with iron cookware and gives the cauliflower a brownish color. To prevent this add some lemon juice to the cauliflower or to the water in which it is blanched.
Cauliflower should be cooked quartered, or cut into florets at the base of the stem. In kitchen lore, lemon juice, milk, flour and vinegar have all been recommended as additions to cauliflower cooking water, presumably to keep it white.
At a minimum, include cruciferous vegetables as part of your diet 2-3 times per week, and make the serving size at least 1-1/2 cups. Even better from a health standpoint, enjoy cauliflower and other vegetables from the cruciferous vegetable group 4-5 times per week, and increase your serving size to 2 cups.
The general rule of thumb is about 20 minutes. Cauliflower that is overcooked will lose up to 50% of its vitamins and minerals. If you want a healthy meal, cook it for just a few minutes less.
The separated florets have to be washed properly under a tap. This removes dirt and large parasites such as worms. The next step is cleaning the cauliflower in mildly warm water in which a little salt was dissolved. This process – which should last 10-20 minutes - destroys several microbes and large parasites.
Baking soda is often used as a natural cleaning agent, and it can be used to brighten up your veggies too. Sprinkle a little in the water before boiling to prevent cauliflower from yellowing and make corn look more vibrant.
Cruciferous vegetables like broccoli and cauliflower contain high levels of insoluble fiber, which can quickly lead to digestive upset, especially when consumed raw. Symptoms can include bloating, gas and cramping.
The best way to deal with the liquid is to put the riced cauliflower in a covered microwave-safe dish, heat it thoroughly to get all the liquid out of it you can, then drain it. If you have to cook it on the stovetop, add as little water as possible and stir frequently to keep it from sticking to the pan.
Dry at 140 degrees F (60°C) in an oven or dehydrator. If necessary, turn large pieces over every 3 to 4 hours during the drying period. Vegetables can scorch easily toward the end of drying, so monitor more closely as drying nears completion.
Other telltale signs of spoilage for cauliflower include mold, off-smells, slimy texture, or soft spots. Per Does it Go Bad?, cauliflower is supposed to be firm to the touch. Once you see soft spots or examples of slimy texture, the cauliflower should definitely be thrown out.
