Christmas morning should feel magical, not stressful. That is exactly why this easy Christmas strata with cheese and roasted peppers was created. You assemble everything the night before, slide it into the fridge, and then bake it fresh while everyone opens gifts. No scrambling at the stove. No juggling three pans at once. Just a bubbling, golden, gloriously cheesy casserole that looks and smells like the holidays.
What makes this version genuinely healthier than a classic strata is the combination of smart swaps that do not sacrifice a single bit of flavour. Instead of white bread soaked in a heavy full-fat dairy custard, this recipe uses whole grain sourdough for extra fibre and a pleasantly tangy bite. The custard base is built from eggs combined with low-fat milk and a generous scoop of cottage cheese, which quietly melts into the mix and bumps the protein content up significantly. Each serving clocks in at around 28 grams of protein and just over 300 calories, which is genuinely impressive for a baked egg casserole. Roasting the peppers brings out their natural sweetness, so you get incredible depth of flavour without needing to add extra salt or fat.
The colour story here is pure Christmas. Red roasted bell peppers and flecks of fresh spinach give you that festive red and green palette without any food colouring or fuss. A layer of sharp reduced-fat cheddar melts into every crevice of the bread, and crumbles of goat cheese add creamy, tangy pockets throughout. Turkey sausage cooked with garlic and smoked paprika brings a savoury warmth that ties every bite together. The smoked paprika is a small but meaningful addition. It adds a subtle smokiness that makes people think the dish is far more complex than it actually is. That is the kind of kitchen secret worth keeping.
This strata is a crowd-pleaser in the truest sense. It serves eight comfortably, making it ideal for a family gathering or a holiday brunch with friends. Leftovers reheat beautifully, so any slices that survive Christmas morning make a lovely Boxing Day breakfast too. The overnight soak is not just a convenience trick. It is actually what gives the strata its signature custard-like interior, as the bread fully absorbs the egg mixture and the whole thing bakes into something between a savoury bread pudding and a puffed egg casserole. Serve it straight from the baking dish with a simple green salad on the side, and you have a festive morning meal that feels both special and effortlessly wholesome.
Ingredients
- 1 tablespoon olive oil (for cooking sausage and vegetables)
- 300 g turkey sausage (casings removed, crumbled)
- 1 teaspoon smoked paprika
- 3 cloves garlic (minced)
- 2 large red bell peppers (roasted, peeled and sliced, see tip)
- 1 large yellow bell pepper (roasted, peeled and sliced)
- 100 g baby spinach (roughly chopped)
- 4 cups whole grain sourdough bread (roughly torn into 2cm cubes, about 8 thick slices)
- 8 large eggs (free range if possible)
- 1 cup low-fat milk (1% or 2%)
- 1 cup low-fat cottage cheese (blended smooth)
- 1 tablespoon Dijon mustard
- 1 teaspoon dried thyme
- 1 teaspoon garlic powder
- 1 teaspoon black pepper (freshly cracked)
- 1 teaspoon sea salt
- 1 cup reduced-fat sharp cheddar (freshly grated, divided)
- 80 g goat cheese (crumbled, divided)
- 3 whole spring onions (thinly sliced, for topping)
Instructions
- 1
Roast your peppers first. Place the whole red and yellow bell peppers directly on a baking tray under a high grill or broiler, turning every few minutes, until the skins are charred and blistered all over. This takes about 15 minutes total. Transfer them to a bowl, cover tightly with a plate or cling film, and let them steam for 10 minutes. Peel away the skins, remove the seeds, and slice the flesh into strips. Set aside.
Roasted peppers from a jar work beautifully here if you are short on time. Choose peppers packed in water or brine rather than oil, and pat them dry before using.

Heat the olive oil in a large non-stick skillet over medium-high heat. Add the crumbled turkey sausage and smoked paprika. Cook, breaking the sausage into small pieces, for about 6 to 8 minutes until cooked through and lightly browned. Add the minced garlic and cook for a further minute. Stir in the chopped spinach and cook just until wilted, about 1 to 2 minutes. Remove the pan from the heat and set aside.
Do not overcook the spinach here. It will continue cooking in the oven, so just a brief wilt is all you need.

Lightly spray or brush a 9x13 inch baking dish with olive oil. Scatter half the torn sourdough bread cubes in an even layer across the bottom. Spread half the turkey sausage and spinach mixture over the bread, then layer half the roasted pepper strips on top. Sprinkle over half the grated cheddar and half the crumbled goat cheese. Repeat the layers with the remaining bread, sausage mixture, roasted peppers, cheddar and goat cheese.
Press the layers down gently with your hands so everything is fairly compact. This helps the custard soak through evenly.

In a large mixing bowl or blender, combine the eggs, low-fat milk, blended cottage cheese, Dijon mustard, dried thyme, garlic powder, salt and black pepper. Whisk vigorously or blend until completely smooth and no lumps of cottage cheese remain. This is your custard base.
Blending the cottage cheese makes it completely undetectable in the final dish. It simply adds creaminess and protein without changing the texture.

Pour the egg custard mixture slowly and evenly over the layered ingredients in the baking dish. Press down gently with a spatula or the back of a spoon to encourage the bread to absorb the liquid. Cover the dish tightly with cling film or a lid and refrigerate for at least 8 hours, or overnight. This soak is what transforms the bread into a custardy, souffle-like interior.
You can refrigerate this for up to 18 hours. The longer soak actually improves the final texture.

When you are ready to bake, remove the strata from the fridge 20 to 30 minutes before cooking to take the chill off. Preheat your oven to 175 degrees Celsius or 350 degrees Fahrenheit. Remove the cling film and scatter the sliced spring onions over the top. Bake uncovered for 50 to 55 minutes, until the top is golden brown, the edges are set, and the centre no longer wobbles when you gently shake the dish.
If the top is browning too quickly before the centre is set, loosely tent a piece of foil over the dish for the last 15 minutes of baking.

Remove the strata from the oven and let it rest for 10 minutes before slicing and serving. This resting time allows the custard to fully set, making it much easier to cut into clean, presentable portions.
Cut into squares rather than scooping it out. A sharp serrated knife works best here.

Pro Tips
- ✓
Blend the cottage cheese completely smooth before adding it to the egg mixture. This keeps the texture silky and ensures no one suspects the secret protein boost.
- ✓
Whole grain sourdough is the best bread choice here. Its structure holds up to the long overnight soak without turning mushy, and the slight tang complements the goat cheese beautifully.
- ✓
If you want to add extra festive colour, scatter a small handful of chopped fresh flat-leaf parsley over the top right before serving.
- ✓
For a cleaner slice, use a thin sharp knife and wipe it between cuts.
- ✓
This strata is best served within 10 minutes of coming out of the oven. The puffed top will settle as it cools, which is completely normal.
Frequently Asked Questions
Variations
- •
Vegetarian Christmas Strata
Skip the turkey sausage entirely. Instead, saute 200g of sliced cremini mushrooms with the garlic and smoked paprika until golden and most of the moisture has evaporated. Use these in place of the sausage for a hearty, fully vegetarian version.
- •
Sun-Dried Tomato and Basil Strata
Swap the roasted peppers for 80g of drained sun-dried tomatoes in water and replace the thyme with 1 teaspoon of dried basil. Scatter fresh basil leaves over the finished strata before serving for a Mediterranean twist.
- •
Spiced Turkey Chorizo Strata
Use chicken or turkey chorizo instead of turkey sausage for a deeper, spicier flavour. Reduce the smoked paprika to half a teaspoon since the chorizo already brings its own spice. This version pairs wonderfully with manchego cheese in place of goat cheese.
Substitutions
- •Whole grain sourdough → Whole wheat bread or multigrain bread (Both work well. Avoid very soft sandwich bread as it can become too mushy during the overnight soak.)
- •Low-fat cottage cheese → Low-fat ricotta cheese (Ricotta blends smoothly into the custard and adds a similar protein boost with a slightly richer flavour.)
- •Turkey sausage → Chicken sausage or chicken and turkey chorizo (Any flavoured poultry sausage works here. Just ensure it is fully cooked in the skillet before layering.)
- •Goat cheese → Reduced-fat feta cheese (Feta has a slightly saltier, sharper tang. If using feta, reduce the added salt in the custard by half.)
- •Low-fat milk → Unsweetened oat milk or unsweetened almond milk (Oat milk gives the closest texture to dairy milk in baked egg dishes. The strata will be dairy-free with this swap combined with dairy-free cheese.)
🧊 Storage
Cool leftovers completely, then cover the baking dish tightly or transfer individual portions to airtight containers. Refrigerate for up to 4 days. Reheat in a 160 degree Celsius oven for 12 to 15 minutes, or microwave individual slices on medium power for 2 to 3 minutes until heated through.
📅 Make Ahead
This recipe is designed for overnight assembly. Prepare and layer everything up to 18 hours ahead, pour over the custard, cover and refrigerate. On Christmas morning, simply bring it to room temperature for 20 to 30 minutes, then bake as directed. The entire hands-on effort on Christmas Day is under 5 minutes.
