Can I use ground beef instead of chunks?
Yes. Brown 1 1/2 pounds ground beef, drain excess fat if needed, then build the gravy the same way. Simmer time can be shorter since you are not tenderizing a roast.
What cut of beef is best for pot pie?
Chuck roast is the sweet spot. It gets tender with a simmer and has enough marbling to stay flavorful. Stew meat works too, but it can be a mixed bag depending on what the store trimmed.
How do I keep the bottom from getting soggy?
This recipe uses a top crust only, which avoids most soggy-bottom issues. If you do a bottom crust, preheat a sheet pan in the oven and bake the pie on that hot pan. Also make sure the filling is thick and not watery before assembling.
Can I make it ahead?
Absolutely. Make the filling up to 2 days ahead. Cool and refrigerate. When ready, rewarm the filling just until loosened (so it spreads easily), top with crust, then bake.
Can I use puff pastry?
Yes, and it is delicious. Thaw puff pastry, lay it over the filling, cut a few vents, egg wash, and bake. Puff pastry browns quickly, so start checking around 20 minutes and expect a range closer to 20 to 30 minutes, depending on thickness and your oven. It is ready when the top is deeply golden and the filling is bubbling at the edges.
My gravy is too thin. What now?
First, simmer uncovered for a few minutes to reduce. If it still needs help, whisk 1 tablespoon cornstarch with 1 tablespoon cold water and stir it in. Simmer 1 to 2 minutes until glossy and thick.
Can I swap the vegetables?
Yes. Mushrooms are great (add with the onions). Green beans work (stir in near the end like the peas). If you add potatoes, dice them small and simmer them with the beef until tender.
