Many health-minded people know that steam-cooking vegetables is preferable to boiling, which leaches the nutrients during cooking. Are you one of them?
I’ve been steaming my vegetables in the microwave ever since I’ve owned that bread-box-sized miracle of technology.
But superheated steam cooking? I hadn’t heard of it until I interviewed Peter Weedfald, Senior Vice President of Sales & Marketing at Sharp Home Appliances. Since 2004, Sharp has sold 2 million superheated steam ovens globally. Who knew?
About two years ago Sharp released its SuperSteam+ Built-In Wall Oven. Recognizing a limited market size for built-ins, Sharp began shipping its first Superheated Steam Countertop Oven in March 2018. “We are going to open up the marketplace with superheated steam, and we want to be the brand and the company under the ribs of the umbrella of “Simply Better Living” to do that,” says Weedfald. Passionate about delivering products that live up to the brand mantle, “Better living includes cooking with superheated steam,” he says. “And the word living is about healthy eating—a healthy lifestyle.”
What Is It?
Sharp’s Superheated Steam Countertop Oven is smaller than a microwave and larger than most toaster ovens. It has a cooking capacity of 0.5 cubic feet. Five cooking modes: toast, warm, bake/reheat, broil/grill, and pizza employ 1,750 watts and temperatures ranging from 160 to 485 degrees Fahrenheit. As a point of reference, microwave oven temperatures reach an average high of 212 degrees. The Superheated Steam Countertop Oven is a compact unit that sits on your counter. It’s not intended to cook a turkey, but it will replace the majority of the tasks you would otherwise need to fire-up your big 5.1-cubic-footer.
“The first big benefit of this counter Superheated Steam Oven compared to any other device you have in the kitchen is it’s, what we call, ‘instant on, no defrost, no preheat,’” says Weedfald. The team did a side-by-side test with a high-end toaster oven to prove the point. We placed two frozen chicken filets in each, set to 485°F superheated steam and 15 minutes later, “the chicken came out perfectly browned on the outside, and moist and delicious on the inside,” says Weedfald. “And guess what? The chicken from the toaster oven was rock-hard.”
Ever the contrarian, I challenged him. “But toaster ovens weren’t made to do that. I would defrost it in the microwave, then cook it in the oven or the grill.” Weedfald fired back: “Go start up a 5-cubic-foot oven, and you wait to preheat it to 485 [degrees], which takes 15 minutes. Then you cook it for 15 minutes. Guess what? I still beat you.” Point taken.
“Number one, you’re using two devices, so you’re paying for electricity on the microwave, and you’re paying for electricity in the oven,” Weedfald adds. “Number two, you’re drying out the food by putting it in the microwave. By the way, if you tell me you want to set it on ‘convection’—convection dries food.”
Yes, been there, done that! Meat defrosted in a microwave oven comes out partially cooked in places, and much of the moisture has been pulled out. The experience has never been good. Like most, I only use the microwave to heat up leftovers.
Weedfald cites one more example. Because he knows I’m skeptical, “Pull a DiGiorno pizza out of your freezer, and read the directions on the back of the box.” The directions read, “Preheat oven and bake at 400°F. Keep pizza frozen while preheating. Place pan directly on center oven rack. Bake 22 to 25 minutes.”
“You have to take a huge five-cubic-foot oven, preheat it for 15 minutes, then wait another 25 minutes for your pizza to cook,” exclaims Weedfald. “You put it into our superheated steam oven, and guess what? In 18 to 22 minutes, bang! You’re done. The crust is brown and crispy, and moist on the inside.”
The next benefit that Weedfald cited was, “I’ve found, by cooking with superheated steam, the texture and the taste of the food is dramatically different than when I cook it in other ovens. It feels like I’m tasting what that salmon should have tasted like when you just pulled it fresh out of the water. The vegetables are absolutely green and fresh tasting.”
The Korean Journal for Food Science of Animal Resources conducted a Comparative Study on the Effects of Boiling, Steaming, Grilling, Microwaving and Superheated Steaming on Quality Characteristics of Marinated Chicken Steak. The findings are below:
- Moisture content and lightness value were higher in superheated steam-cooked chicken steak than that of boiling, grilling, and microwave cooking.
- Superheated steam samples scored the highest among the sensory characteristics, tenderness score, juiciness score and overall acceptability score for chicken steak.
- Superheated steam improved the quality characteristics and sensory properties of marinated chicken steak.
Research supports the benefits. The U.S. National Library of Medicine National Institutes of Health investigated the effects of five domestic cooking methods, including steaming, microwaving, boiling, stir-frying, and stir-frying followed by boiling (stir-frying/boiling), on the nutrients and health-promoting compounds of broccoli. Results show that all cooking treatments, except steaming, caused significant losses of chlorophyll and vitamin C and significant decreases of total soluble proteins and soluble sugars.
5 Reality Bites
Looking at the data, there’s good reason for the selection of frozen prepared foods on the Superheated Steam Countertop Oven cooking times chart, and kitchen appliance retailers should take notice.
$4.42 billion was spent on frozen pizza by Americans in 2015(1)
10 frozen pizzas per month or more were consumed by 19.25 million Americans in 2018 (2)
$72.98 billion by 2024: Overall frozen food market in the U.S. (3)
$21 billion annual sales projected for 2016-2021 in the four key frozen food categories: frozen dinners/entrées; frozen pizzas; frozen side dishes; and frozen appetizers/snacks. (4)

Do We Need Another Cooking Appliance?
This was my unabashed question. Weedfald fires back, “What do you do to create a healthier environment? Which mode of cooking do you use most at home? Is it the big 5-cubic-foot oven? Is it a toaster oven? Is it a regular toaster? Is it a microwave? Is it over-the-counter? Which of the following best describes your perception of cooking with steam? Do you have a perception of cooking with steam? What’s the number one biggest time issue with cooking? What takes you the most time to get cooking? What are your concerns about cooking frozen pizza?” These are the same questions he put in a survey to 1,003 randomly selected consumers (not Sharp customers). Below is a snapshot:
1,003 Consumers Surveyed
48% Male; 52% Female
35% Baby Boomers; 26% Gen-X; 31% Millennials; Other 8%
View Steam-cooking as Healthy: 47% All Respondents
Currently Use Steam to Cook: Baby Boomers 4%; Millennials 3%
Barriers to Entry:
79% percent have quality concerns with frozen pizza (Millennials have the highest concern at 81%).
33% Consider preheat and defrost as their biggest time issue.
27% Weary of cooking with steam due to time and flavor concerns
I’m a born skeptic and conducted my own survey, because I am hard-pressed to believe frozen pizza is that popular when there’s no shortage of “Main Street House of Pizza” in America. My neighbors are highly educated Millennials who I consider model parents. Both have degrees in nutritional science. Their kids are 10 and 12 years old. They don’t eat junk food or McDonald’s. They don’t have smartphones or iPads. They play outside. I asked Kim if she has ever purchased a frozen pizza. “Are you kidding? We keep Costco pizzas in the freezer because sometimes we just don’t have time.”
“We now live in the instant gratification economy,” says Weedfald. He’s right, and my model Millennial neighbors are no different.
Takeaways: The Superheated Steam Countertop Oven replaces a toaster oven, displaces the use of a large standard oven saving energy, no need to preheat the oven because it’s “instant on,” no need to defrost in the microwave because you can put food straight from the freezer and cook it without time added to the overall process, brown on the outside, and moist on the inside. To me, it sounded too good to be true (see my non-review here).
Weedfald waxed poetic about the health benefits of cooking with steam. I downloaded the cooking times chart for the Superheated Steam Countertop Oven and was disappointed to see frozen processed foods such as pizza, jalapeno poppers, French fries, breaded shrimp, and chicken nuggets, occupying 26 out of 33 items. Only four of the 33 foods noted would be considered healthy options by most.
Not to despair, Americans are also opting for heathy frozen foods. A recent article published by NPR states, “As for the assumption that fresh is healthiest, it turns out that frozen produce can pack a punch when it comes to nutrition. When you freeze fruits and vegetables, it locks in nutrients, and several studies have shown that this helps retain high levels of vitamins.” Citing a report from RBC Capital Markets, “the uptick is new — and modest. But growth ‘is accelerating as consumers begin to see freezing as a way to preserve food with fewer negatives.’”
