Hi Loretta,
Thank you for reaching out and we hope you are in good health. We appreciate your interest in Samsung home appliances, specifically with Samsung - 1.7 cu. ft. Over-the-Range Convection Microwave with WiFi - Stainless steel.
The simple answer is yes; you can use this microwave as an oven. However, for that to be possible, you need to have convection function in the microwave. In microwaves that come with a convection mode, the appliance will behave like any regular oven and can be used to bake bread, cakes, cookies, or anything else you would want to bake.
I have shared the user manual link below. Please access the link and turn to page 51 for the convection function.
