Smoked breakfast casserole with sausage and hash browns

October 25, 2026

A smoked breakfast casserole is a pan of browned sausage, hash browns, cheese, and beaten eggs cooked on a smoker at about 300 to 325°F for 60 to 90 minutes, until the center reaches 160°F. It feeds 8 to 10 people, picks up a light smoky flavor, and can be assembled the night before so the morning is just lighting the cooker.

Ingredients

This fills a 9x13-inch pan. A disposable aluminum pan works well on a smoker and saves your good bakeware from smoke stains.

  • 1 pound bulk breakfast sausage
  • 1 small onion, diced
  • 1 bell pepper, diced
  • About 4 cups frozen shredded hash browns, thawed (roughly a 20 to 30 ounce bag)
  • 2 cups shredded sharp cheddar, divided
  • 12 large eggs
  • 1 cup whole milk or half-and-half
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon smoked paprika (optional)
  • Sliced green onions for serving

Steps

  1. Brown the sausage in a skillet over medium heat, breaking it into crumbles, for 8 to 10 minutes until no pink remains. Add the onion and pepper for the last 3 to 4 minutes. Drain off excess fat.
  2. Grease the pan. Spread the thawed hash browns in an even layer and season them lightly with salt.
  3. Scatter the sausage mixture over the potatoes, then 1 1/2 cups of the cheese.
  4. Whisk the eggs, milk, salt, pepper, garlic powder, and paprika until smooth. Pour evenly over the pan.
  5. Cover and refrigerate overnight if making ahead, or move straight to the smoker.
  6. Preheat the smoker or pellet grill to 300 to 325°F with a mild wood like apple, cherry, or pecan.
  7. Set the pan on the grate, uncovered, and cook for 60 to 90 minutes. A pan that went in cold from the fridge sits at the longer end.
  8. Add the remaining cheese for the last 10 minutes.
  9. Check the center with an instant-read thermometer. It's done at 160°F, when the middle is set and no longer jiggles like liquid.
  10. Rest for 10 minutes before cutting so the eggs firm up and slice cleanly.

What temperature should I smoke a breakfast casserole at?

Around 300 to 325°F works well for most smokers. At classic low-and-slow temps of 225 to 250°F, an egg casserole can take well over 2 hours, and the edges tend to dry out before the middle sets. Running a little hotter cooks the eggs through in a reasonable time while still giving the top some smoke. If your cooker struggles to hold 300°F, plan on more time and check the center often.

Which wood works best for breakfast?

Mild fruit woods are the safe pick. Eggs, cheese, and potatoes absorb smoke fast, and strong woods like mesquite or a lot of hickory can make the casserole taste bitter. Apple, cherry, pecan, or a competition blend of pellets all work. You want a thin, clean smoke, not thick white billows.

Can I assemble it the night before?

Yes, and it's the easiest way to do it. Assemble the casserole through step 4, cover it with foil, and refrigerate it for up to 24 hours. The potatoes soak up some of the egg overnight, which gives a firmer, sliceable casserole. Take the foil off before it goes on the smoker so the smoke can reach the top.

Keep the assembled pan in the fridge until the cooker is ready rather than letting it sit out while the smoker heats up.

How do I know when it's done?

The center should read 160°F on a thermometer, which is the temperature the USDA recommends for egg dishes. Visual cues help too: the middle should be set and puffed, a knife inserted near the center should come out without liquid egg, and the edges should be lightly browned. If the top is browning too fast before the center is done, lay a loose piece of foil over it.

Swaps and variations

  • Swap the sausage for 1 pound of chopped bacon cooked until crisp, or diced ham (no browning needed).
  • Use pepper jack for a spicier casserole, or a mix of cheddar and Monterey Jack for a softer melt.
  • Replace the hash browns with 6 to 8 cups of cubed day-old bread for a strata-style casserole.
  • Add a can of drained diced green chiles or a handful of sautéed mushrooms.
  • If you've made a breakfast fatty and have leftovers, chop them up and use them in place of the sausage.

Leftovers and food safety

Refrigerate leftovers within 2 hours of coming off the smoker. Covered, the casserole keeps for about 3 to 4 days. Reheat single slices in the microwave or a covered skillet until hot in the center. The casserole also freezes well in individual portions wrapped tightly; thaw in the fridge overnight before reheating.

Whenever you work with raw sausage, wash hands and boards afterward, and don't let the raw meat touch the cheese or other ingredients you'll add later without cooking.

Can I make it on a gas grill?

Yes. Set up the grill for indirect heat by lighting the burners on one side and placing the pan on the other, aiming for 300 to 325°F on the lid thermometer. Add a foil packet or smoker box of wood chips over the lit burners for smoke flavor. Rotate the pan halfway through, since the side nearest the flame cooks faster.
