Ingredients for Mushroom Stuffing
Of course one of the most important ingredients in stuffing is bread. It is so important that we devoted a whole section on it below. You can pop down there and read more about it:
Pancetta – Italian cured pork that's similar to bacon but unsmoked, giving it a rich, salty flavor without the smokiness (you can sub bacon if you want the extra smokiness). It adds a wonderful layer of flavor and texture. When crisped up first, its rendered fat becomes the perfect base for sautéing onions, garlic, and mushrooms.
Cremini Mushrooms – also called Baby Bella mushrooms are perfect for your Herbed Mushroom Stuffing. They are meaty and flavorful and will stand up to the sautéing and baking.

Onion & Celery - It's CLASSIC to have onion and celery added to your stuffing. You can use the celery ribs and leaves!
Garlic – a couple garlic cloves are chopped and sauteed with the mushrooms. The flavor pairs perfectly with the pancetta, mushrooms and rosemary.
Egg - The eggs will bind the stuffing together for the perfect texture.
Chicken Broth - Using the right amount of chicken broth moistens the dried bread cubes perfectly, so that they are buttery and soft in the middle, and not soggy.
Herbs - Fresh herbs help create an over-the-top flavor. Chopped sage, rosemary and parsley pair perfectly with the mushroom and pancetta.
Seasonings - The fresh herbs do most of the heavy lifting in this Mushroom Stuffing, but a little kosher salt, black pepper, and poultry seasoning enhance all the flavors.
Salted Butter - The salted version is the only butter we recognize here at Mom's Dinner.
Bread Cubes
Bread is one of the main ingredient in Mushroom Stuffing. So you want to make sure that you buy a good quality bread that will stand up to the butter, eggs and broth that are added.
Look for a thicker cut bread. I have used these brands and they work perfectly: Sara Lee Artesano or Pepperidge Farm Hearty White.

You will also want to make sure that your bread is stale. This is key to allowing the bread to absorb the butter, broth and eggs, which makes your stuffing so buttery and golden! If the bread isn’t properly stale it will disintegrate when you add the liquids.
How TO Make Stale Bread Cubes
There are two options for making stale bread. Make sure to dry the cubes so they feel and sound almost like a crouton…
- Days in Advance- Cut the bread into 1 inch cubes and let it sit on a sheet pan or two, on the counter for a couple days. If it isn’t totally dry by the time you need it, pop it in a 200°F oven for 15 minutes.
- Quick Method- Cut the bread into 1 inch cubes and spread on a large sheet pan or two. Dry in a 250 degree oven for 30-40 minutes, tossing every 5-10 minutes so it doesn't brown.
