How to make sweet potato casserole not runny? ›

Eggs and cream help stabilize the dish and prevent it from becoming too runny (a common complaint with many sweet potato casserole recipes). Make it as smooth or chunky as you like!

A really good sweet potato casserole filling should be light and moist, not dense. If it's dense, then you may not have added an often overlooked ingredient—an egg. An egg adds lift, structure and volume and makes the filling more custard-like.

Sprinkle the topping evenly over the sweet potato mixture, then pop it into the oven and let it bake for 40 to 45 minutes. You will know it's done when the topping is lightly browned and the center of your casserole is set and firm.

Canned or frozen sweet potatoes may be substituted for the fresh form in any recipe calling for cooked sweet potatoes as the starting point. Canned sweet potatoes are generally smaller in diameter because of their better canning qualities.

Simply whisk equal parts butter and flour together. Then, roll the thick paste into little teaspoon-sized balls. Add one ball to your casserole at a time, waiting about a minute before adding another one, until you get the right thickness.

Try different herbs for added flavour: sage or lemon thyme work wonderfully well. For a meatier casserole, add chopped sausage or pancetta when cooking the chicken. Stir wholegrain mustard through the casserole at the end of cooking (to taste); this is especially good if you have sausage in the casserole.

The solution for watery casseroles is instant potato mash powder or cornflour - slake (mix with a little water) at first or it will go lumpy. Stir well. Alternatively, don't add so much water at first, especially if you're using a slow cooker.

If the potato is still firm when squeezed, that means it needs to cook more. Baked sweet potatoes can be stored in an airtight container in the refrigerator for up to 5 days. Reheat for 2 minutes in the microwave, at 400°F in the air fryer for 5 minutes, or at 400°F in the oven for 10 minutes.

If your sweet potato casserole turned out “watery”, its usually because you forgot to add eggs; you didn't let your casserole have enough time to set up after baking or you used fresh sweet potatoes and didn't boil them long enough before mashing.

Can you eat sweet potato casserole left out overnight? ›

Cooked sweet potato should be kept in the refrigerator and eaten within 5 to 7 days, says Richard. "Cooked food should not sit at room temperature more than two hours before putting it in the refrigerator or freezer (or one hour when the temperature is above 90°F)," she notes.

Sweet potatoes stored at temperatures above 60 degrees Fahrenheit will shrivel and become dry and stringy. Sweet potatoes may develop an off-flavor and the flesh may become discolored when stored at temperatures below 55 degrees Fahrenheit.

We decided to use a medium sweet potato for our measurements. We found that it took 1.25 medium sweet potatoes to obtain 1 cup of sliced potato. When cubing, we needed 1.3 sweet potatoes to reach the 1 cup mark. However, when measuring for 1 cup of mashed, 2 whole sweet potatoes did the trick.

One pound raw fresh sweet potatoes = 3 cups shredded, cubed or sliced = 1 3/4 cups cooked, mashed.

Leaving the syrup on the yams can hamper their taste. Rinsing sweet potatoes of any leftover sugary film will uphold their integrity, giving you the most authentic sweet potato taste and texture.

The casserole needs at least 15-20 minutes to cool before serving. The casserole sets up as it cools. However, if you prefer a really thick sweet potato casserole, you can add about 2-3 tablespoons of flour to your sweet potato batter and this will help the mixture to thicken.

My sauce is watery

If you stored your potatoes in water to prevent discoloring, be sure to drain them well and pat them dry before adding to your casserole. Some of the waxier potatoes can release more water than starchier ones, so look for good baking potatoes like russet or Yukon golds.

Try letting the dish rest for 10 minutes or so to let the water get absorbed and let the sauce thicken. Try cooking your recipe longer.

Sprinkle the pecan topping mixture over the top of the sweet potato filling. Bake the casserole for 35 to 45 minutes, until the filling is hot, does not jiggle when you shake the dish, and the topping has browned.
