Is Swedish meatball sauce the same as gravy?
Pretty much, but it is usually creamier and often has a little tang (like Dijon) and warm spice (sometimes nutmeg or allspice). Think gravy with a soft Scandinavian accent.
What if I do not have heavy cream?
Half-and-half works well. Whole milk also works, but the sauce will be slightly thinner and less rich. If using milk, simmer a bit longer to tighten it up.
Can I make it gluten-free?
Yes. Swap the flour for a 1:1 gluten-free all-purpose flour blend, or thicken at the end with a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon cold water, then whisk in and simmer until glossy). For a truly gluten-free sauce, use gluten-free Worcestershire and tamari instead of regular soy sauce (and always check labels).
How do I keep the sauce from getting lumpy?
Whisk the flour into melted butter until smooth, then add broth slowly while whisking. If lumps still happen, do not panic. Strain it or hit it briefly with an immersion blender.
Can I double this recipe?
Absolutely. Double everything and use a wider skillet or a medium saucepan so it thickens evenly. The only thing that changes is time: you may need a few extra minutes of simmering to reach that spoon-coating thickness.
What should I serve it with besides meatballs?
Mashed potatoes, egg noodles, rice, roasted mushrooms, or even over crispy smashed potatoes. It is also excellent on meatloaf if you are in the mood for comfort food that goes big.
