Is there anything cozier than baking bread on a cold, windy day? While it’s my favorite time to bake, it’s also when readers struggle most with dense bread.
Why Proofing Dough Can Be Challenging in Winter
Cold temperatures can slow yeast activity, resulting in dense, underproofed bread. For bread machine users, this can cause baking to start before the dough has properly risen, leading to disappointing results. A warm, draft-free environment is key to successful proofing, but sometimes your bread machine’s warming element isn’t enough.
Two Easy Solutions for Cool Temperatures
#1: Move your machine to a warmer spot in the house.

- Position the machine in a warm, humid area, ideally 75-78°F (24-26°C).
- Use a quick-read thermometer (paid link) to monitor dough temperature.
#2: Cover Your Bread Machine with a Towel or Blanket

- Drape a large towel or blanket over the machine during the DOUGH cycle to retain warmth.
- If baking in the machine, remove the cover before the preheat phase to avoid overheating.
Using Your Microwave as a Proofing Box
The microwave provides a warm, humid, and draft-free environment ideal for proofing dough.

Step-by-Step Instructions
- Heat a cup of water in the microwave on HIGH for 2 minutes.
- Leave the mug in one corner of the microwave.
- Place your uncovered dough inside the microwave and close the door.
- Do not turn on the microwave with the dough inside.
Cautions When Proofing Dough in a Micowave:
- Avoid Superheating Water:
- Superheating can cause water to erupt when disturbed. To prevent this, place a silicone spatula in the cup while heating.
2. Watch for Overproofing:
- A steamy microwave can accelerate proofing. Check the dough regularly and set a timer to avoid overproofing. (It’s easier to forget about your dough when you don’t see it sitting on the counter.)

Why I Don’t Recommend Proofing Dough on LOW Power
Heating dough on LOW power (as some people suggest) may seem like a shortcut, but it sacrifices flavor. A slow, natural rise is ideal for developing the complex flavors in yeast bread.
A long, slow rise imparts the best flavor to yeast bread. When possible, don’t rush it.

FAQs About Proofing Dough
Can I use my oven as a proofing box?
Yes! Heat your oven to 100°F (37°C) or place a pan of hot water inside for warmth.
Do I need to cover the dough while it proofs?
Covering is optional in a humid microwave but recommended elsewhere to prevent drying.
How long does the microwave stay warm?
The microwave remains warm for about 15-30 minutes, depending on the room temperature and the microwave itself.

I also use the microwave, but in a different way. However, I will surely try the hot water method 🙂
Cool! Great article!
I have a bread proof cycle on my
oven. We have below zero temperatures right now. I put boiling water in a pan on the bottom rack of the oven and put the bread proof cycle on. The bread rises without any problems.
Hi Jill,
Nice to hear from you again. Thank you for adding to the conversation. The boiling water in a pan inside your oven is a great idea to increase the humidity.
Paula, thank you so much for all of your wonderful tips. I am relative new to baking bread and have had so much fun from your recipes. I made the pretzel rolls last week. They were so easy and turned out great!
Your recipes have been easy to follow and I am having so much fun. Never let it be said that at 80 you cannot learn new things!
Hi Judy,
If I make it to your age, I hope I have the same thirst for new adventures in the kitchen that you have. Thank you for taking the time to write such kind words about my recipes. Have a great week!
I enjoy making all kinds of bread. When I need to bulk rise my sourdough bread or even after I feed my sourdough starter I place it on my instant pot trivet (it’s high and stainless steel) and put it on my cooktop warming center. This allows it to rise but not be exposed to direct heat! It’s been a good solution for my cool kitchen. I do keep the hood light on as well so it’s getting warm from both directions. Keeping it in a clear glass bowl and marking it has helped too.
Hi Lindsay,
This is a brilliant idea. I use my instant pot trivet for cooling bread but never thought about it for rising. The hood light is another possibility I haven’t tried. That reminds me of how I keep sourdough starter warm by placing it close to my undercabinet lights. Works great. I had forgotten all about that until I read your letter.
Your tip about the clear glass bowl and marking it is also very smart.
Thanks so much for sharing.
