How do you thicken up cottage pie? ›

Flour power

A classic thickening method for a classic dish. A few tablespoons of flour, cooked-out so you can't taste it, turns a thin sauce into a velvety gravy of dreams.

If your gravy is on the skimpy side, you can thicken it quickly with flour or cornstarch. But don't add your thickener directly to the gravy, which will create lumps. Instead, try stirring in three or four tablespoons of flour or cornstarch into a small amount of cold water until you have a smooth paste.

Residual moisture from the potatoes will drip into the beef below as it cooks, and too much of it will cause the potatoes to eventually sink. Aside from ridding your potatoes of excess moisture before you mash them, it also helps to cool the beef down, BBC Good Food shares.

The three main thickening agents for gravies are flour, cornflour and arrowroot. The first two are normally used in savoury dishes while arrowroot tends to be used in sweet dishes – that said, arrowroot will work in a savoury dish as it has no flavour.

Bake the fruit pie at a high temperature.

If you don't bake your pie at a high enough temp your thickener doesn't get to the necessary temperature for a long enough time to thicken your filling. Also, that high temp is needed to get your pie crust light & flaky.

Place a fine-holed sieve or one with a large coffee filter in it over a bowl, pour in the cottage cheese and leave the liquid to drain out into the bowl that is the whey; the thicher portion in the sieve can be left in large curds, or smashed with a fork, to make a finer curd.

After cooking the beef, onion, and herbs, be sure to drain the grease out of the pan. Otherwise, you will find yourself with a greasy shepherd's pie. Stir well. Especially when adding the flour and tomato paste.

Cottage pie uses minced lean ground beef as its base and beef broth as its gravy. Shepherd's pie, on the other hand, uses ground lamb, and the juices of the minced lamb become the gravy for this comfort food.

To stop the mash sinking into the filling, allow the meat to cool before topping with the mashed potato. Freeze in individual ovenproof dishes for an easy meal for one. For a really crisp, golden topping, flash under the grill for a few mins before serving.

Browning adds more flavor to the gravy and gets rid of the raw flour taste. You're basically making a roux. We find that a flour-based gravy holds up better and reheats better later, which is why we tend to prefer using flour over cornstarch to make gravy unless we have a guest who is eating gluten-free.

How to thicken gravy without cornstarch or flour? ›

Gums: You can also use vegetable gums, such as xanthan gum or guar gum, to thicken sauces. Xanthan gum and guar gum are very powerful, so use minimal amounts—too much can make the sauce slimy or unpleasantly chewy. 7. Potato starch: You can use potato starch in place of cornstarch with a one-to-one ratio.

Cornstarch makes for a shiny, glossy filling. A little goes a long way because it has twice the gelling power of flour. Flour thickens nicely but leaves more of a matte finish. You'll need to use twice as much as you would with cornstarch.

Experiment with different thickeners

If you usually use flour to thicken your apple pie and it's not doing the job, try something different: cornstarch, tapioca, and arrowroot are other established fruit pie thickeners. For more on specific thickeners and how to use them, see our Pie Filling Thickeners Guide.

– Secondly, you can add in some cornstarch to thicken up the frosting. I would add in about 2 tablespoons max, otherwise it can start to impact the taste/texture of your frosting. – You can also add in meringue powder or arrowroot powder. About 2 teaspoons of each per batch of frosting.
