This simple Spaetzle with Bratwurst Sweet Potatoes and Caramelized Onions brings together German comfort with warm fall flavors. Equal parts creamy and savory this recipe transforms a humble collection of fridge and pantry staples into a cozy family dinner. I love how every bite pairs golden onions with roasted sweet potato and gooey pools of melted cheese wrapped around those tender spaetzle dumplings.
I discovered this dish while hunting for something comforting to stretch out a pack of bratwurst and clean out the veggie drawer. Now my friends beg me to make it at every fall get together because it feels both special and familiar.
Ingredients
- Butter: creates a rich base for caramelizing the onions so quality unsalted butter keeps flavors clean
- Sweet yellow onion: brings natural sweetness deepened during caramelizing I look for large onions with tight skins and no green shoots
- Sugar: a pinch accelerates the hoigh flavor browning in the onions any basic granulated sugar works
- Sweet potato: adds earthiness and creamy texture to balance the savory I choose smaller firm sweet potatoes so they roast evenly
- Olive oil: helps sweet potato cubes get a crisp edge and facilitates roasting Extra virgin gives deeper flavor
- Salt and pepper: essential for seasoning every layer use kosher salt and cracked black pepper whenever possible
- Bratwurst links: classic German sausage for smoky hearty bite I choose uncooked links for best texture
- Cooked spaetzle: little dumplings that soak up all the flavor You can use a good quality dried or fresh store bought or homemade spaetzle
- Havarti cheese: mild and creamy with meltability I buy a block and grate it fresh for best results
- Gruyere cheese: nutty and deep flavor adds dimension Grating your own from a wedge ensures the best melt
- Fresh sage: gives herbal autumn aroma and pops of color Look for bright unwilted leaves
Step-by-Step Instructions
- Caramelize the Onions:
- In a large skillet over medium low heat melt the butter then add the sliced onions and a pinch of sugar Stir gently to coat all slices evenly Let the onions cook uncovered for at least thirty minutes only stirring every five to eight minutes to prevent burning They should turn deep golden and soft which pulls out their natural sweetness
- Roast the Sweet Potato:
- Preheat your oven to four hundred and twenty five degrees Toss the sweet potato cubes with olive oil salt and pepper till each piece is well coated Arrange in a single layer on a baking sheet Roast for around twenty minutes until the cubes are soft golden at the edges and can easily be pierced with a fork
- Cook the Bratwurst:
- Using a sharp knife slice the bratwurst links lengthwise then peel away and discard the casings Crumble the sausage meat into a skillet set over medium heat Break it up with a wooden spoon and cook until there is no pink left and the pieces are browned This should take about ten to fifteen minutes Transfer the cooked bratwurst to a plate lined with a paper towel to soak up excess grease
- Assemble and Layer:
- Grease a large baking dish around nine by thirteen inches or use a twelve inch cast iron skillet for rustic presentation Begin with half the spaetzle evenly distributed across the bottom Sprinkle half of the grated havarti and gruyere over this Next layer half each of the cooked bratwurst crumbles roasted sweet potato cubes and caramelized onions Repeat with another layer of all ingredients so the top has plenty of cheese and veggies
- Bake to Finish:
- Preheat your oven to four hundred degrees Place the assembled baking dish uncovered in the oven and bake for fifteen to twenty minutes The dish is ready when the cheese is melted and bubbling and edges turn a bit brown Serve immediately topped with a generous handful of fresh chopped sage for a true autumn finish

Caramelized onions are my absolute favorite in this dish I love watching them change color slowly on the stove The aroma fills the whole kitchen and brings back memories of cooking with my grandmother She used to let me sneak a taste as they cooked
Storage Tips
Let the dish cool completely then cover well with foil or transfer into airtight containers for the fridge It keeps for about four days If you plan to freeze spoon leftovers into individual microwave safe containers and they will keep for up to three months To reheat bake or microwave until hot through I find the flavors deepen and become even more comforting the second day
Ingredient Substitutions
For an easy switch try chicken or turkey sausage in place of bratwurst For cheese lovers fontina or swiss can sub in for havarti or gruyere If you do not have sweet potatoes use butternut squash or even roasted carrots Spaetzle is traditional but you can use small cooked pasta shapes in a pinch
Serving Suggestions
