Turkey Tetrazzini with Wild Mushrooms and Peas

Why This Turkey Tetrazzini with Wild Mushrooms and Peas Works

During cooking, the butter, onions, garlic, and mushrooms turn into a soft base that soaks up the flour. Once the chicken broth and cream go in, that flour starts to swell and thicken the liquid. After a few minutes, the sauce goes from thin and runny to smooth and creamy, so it can cling to every strand of spaghetti instead of sliding off.

As the turkey and peas warm in that sauce, the turkey stays moist instead of drying out in the oven, and the peas heat through without getting mushy. When the spaghetti is tossed in, the starch on the pasta grabs onto the thick sauce, so everything holds together instead of separating into dry pasta and a puddle of cream.

In the oven, the top layer of Parmesan and breadcrumbs dries out and crisps up while the inside stays soft and saucy. By the time it comes out, there is a contrast between the crunchy top and the creamy pasta underneath, which keeps each bite from feeling heavy or gluey.

Mistakes To Avoid

Boiling the spaghetti until it’s very soft makes the whole bake mushy. Once it goes into the oven with hot sauce, the pasta keeps softening, so instead of separate strands, it turns into a heavy, gluey mass that doesn’t reheat well.

Letting the sauce stay thin before mixing in the turkey and pasta causes trouble in the oven. A runny sauce doesn’t cling to the spaghetti, so the turkey and peas dry out on top while the liquid sinks to the bottom and pools there.

Adding the peas too early to the pan, while the sauce is still thickening, leads to peas that are shriveled and dull by the time the dish comes out of the oven. They lose their pop and turn a bit tough instead of staying soft and bright.

Skipping the drizzle of olive oil over the breadcrumbs often leaves the top pale and dusty. The crumbs don’t really crisp, so instead of a crunchy lid, the casserole gets a dry, sandy layer that falls off in chunks.
