Why Does My Oven Burn My Biscuit Bottoms?

If your oven is consistently burning the bottoms of your biscuits, there are several common reasons for this issue:

1. Temperature Too High: Baking biscuits at a temperature that’s too high can cause the bottoms to burn before the tops are fully cooked. Ensure that you’re following the recommended temperature in your biscuit recipe.
2. Improper Rack Placement: Placing your biscuits too close to the bottom of the oven can expose them to intense heat, leading to burning. Use the middle oven rack for more even cooking.
3. Dark Baking Sheet: Using a dark-colored baking sheet can cause biscuits to absorb more heat, which can lead to burning on the bottom. Consider using a lighter-colored or insulated baking sheet instead.
4. Lack of Insulation: Insufficient insulation in your baking sheets or pans can lead to uneven heating. This can result in the bottoms of biscuits getting too much direct heat. Invest in quality baking sheets with good insulation.
5. Overcrowding: Overcrowding the baking sheet with too many biscuits can hinder air circulation in the oven, leading to uneven cooking. Leave enough space between biscuits for proper airflow.
6. Not Preheating the Oven: Failing to preheat the oven before baking can cause uneven cooking. Make sure to preheat your oven to the specified temperature in your recipe before placing the biscuits inside.
7. Uneven Oven Temperature: Ovens can have temperature variations, with some areas being hotter than others. Consider using an oven thermometer to verify that your oven is heating accurately. If there’s a significant discrepancy, you may need to calibrate the oven or have it serviced.
8. Baking Time Too Long: Overbaking biscuits can lead to burning, especially on the bottom. Follow the recommended baking time in your recipe and check for doneness a few minutes before the minimum suggested time.
9. Excessive Fat or Butter: If your biscuit dough contains too much fat or butter, it can melt and pool at the bottom, causing burning. Make sure to follow your recipe’s measurements accurately.
10. Wrong Oven Setting: Ensure you’re using the correct oven setting (e.g., bake, not broil) for baking biscuits. Using the wrong setting can result in uneven heating.
11. Oven Hot Spots: Some ovens have hot spots where the heat is concentrated. Rotate your baking sheet halfway through the baking time to promote even cooking.

What’s Causing My Oven To Overheat?

An oven overheating can be a concerning issue as it not only affects your cooking but can also be a safety hazard. Several factors can cause an oven to overheat:

1. Faulty Thermostat: The thermostat is responsible for regulating the oven’s temperature. If it’s malfunctioning or inaccurate, it may allow the oven to heat beyond the set temperature, causing overheating.
