Enchiladas are typically prepared with corn tortillas, but my husband, Jeff, and I prefer flour tortillas. I use them in this saucy casserole that has irresistible home-cooked flavor and a subtle kick.

Flour tortillas demand specific handling when substituted for traditional corn because their high gluten content reacts differently to moisture and heat. Standard corn tortillas rely on nixtamalization to hold their shape under heavy sauces, whereas flour varieties soften quickly and risk tearing if overfilled. Maintaining a precise measurement of one quarter cup of beef mixture per six-inch tortilla prevents structural blowouts during the rolling phase. Standardizing the fill volume ensures each piece fits snugly into a thirteen by nine inch baking dish without overlapping awkwardly.
Baking this casserole requires a heavy glass or ceramic pan rather than thin aluminum sheeting. Glass retains heat evenly, protecting the butter-and-flour roux sauce from scorching during the initial thirty-minute covered bake at three hundred fifty degrees Fahrenheit. Aluminum can create hot spots that break emulsions in dairy-heavy sauces, causing the cheese and tomato base to separate into a greasy film. Covering the dish tightly with foil traps steam, ensuring the interior reaches a uniform temperature before the final uncovered melt phase.
Raw minced garlic cooked briefly in foaming butter undergoes a Maillard reaction that softens its harsh bite, yielding savory pyrazines before the broth is added. Combining this roasted garlic base with stewed tomatoes introduces natural glutamates and citric acid that cut through the substantial fat content of the ground beef and Colby-Monterey Jack cheese. Whisking the flour directly into the melted butter and cooking it for two full minutes eliminates raw starch flavors, producing a velvety binder that thickens the broth and tomato sauce without forming lumps.
